The spinal cord contains meninges and is made up of laminae and nuclei. It contains ascending and descending pathways that connect the periphery to the brain. The two major ascending pathways are the dorsal column system and spinothalamic tract, which transmit sensory information from the body to the brain. Other important pathways include the corticospinal tract.

This document summarizes the corticospinal and corticobulbar pathways. The corticospinal pathway involves upper motor neurons in the cerebral cortex that project down the lateral white matter of the spinal cord to lower motor neurons controlling distal limb muscles. The corticobulbar pathway involves upper motor neurons in the brainstem that project bilaterally to motor nuclei controlling axial and proximal limb muscles. Both pathways cross the midline, with the corticospinal pathway having a 90-95% contralateral projection and 5-10% ipsilateral projection.Jeopardy

The inner ear is composed of an osseous portion containing fluid and structures like the cochlea and semicircular canals, and a membranous portion containing additional fluid and structures such as the saccule and utricle. The inner ear consists of the vestibular portion for balance and the cochlear portion for hearing, with the cochlea being a spiral shaped structure that converts sound into electrical signals through hair cells. The cochlea contains three fluid filled canals and uses traveling waves that vary in amplitude at different points along the basilar membrane to detect different frequencies of sound.13.vestibular apparatus kjg

The document summarizes the vestibular system which is involved in maintaining equilibrium and balance. It describes the three main systems - vestibular, visual, and proprioceptive. The vestibular system contains the semicircular canals and otolith organs which detect head movement and gravity. The hair cells in each organ bend to detect rotational or linear acceleration and send signals to the brain. Disorders like nystagmus and vertigo can result from vestibular problems. Together, the three systems allow the brain to integrate sensory information and coordinate muscle movements to keep the body balanced.Cerebellar connections - Physiology

The human brain is the central organ of the human nervous system, along with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem as well as the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and guarded by, the skull bones of the head.
The cerebrum is the largest of the human brain. It is divided into two cerebral hemispheres. The cerebral cortex is an outer layer of grey matter, covering the core of the white matter. Each hemisphere is conventionally divided into four lobes the frontal, temporal, parietal, and occipital lobes. Within each lobe, cortical areas are associated with specific functions, such as the sensory, motor and association regions. Although the left and right hemispheres are broadly similar in shape and performance, some functions are related to one side, like language within the left and visual-spatial ability on the right. The hemispheres are connected by the corpus callosum.
The brainstem consists of the midbrain, the pons, and the medulla oblongata. The cerebellum is connected to the brainstem by pairs of tracts. Underneath the cerebral cortex are several important structures, including the thalamus, the epithalamus, the pineal gland, the hypothalamus, the pituitary gland, and the subthalamus; the limbic structures, including the amygdala as well as the hippocampus; the claustrum, various nuclei of the basal ganglia; the basal forebrain structures, and the three circumventricular organs. The cells of the brain include neurons and supportive glial cells. There are more than 86 billion neurons within the brain. Brain activity is possible by the interconnections of neurons and their release of neurotransmitters in response to nerve impulses. Neurons connect to form neural pathways, neural circuits, and elaborate network systems. The whole circuitry is driven by the method of neurotransmission.
The study of the anatomy of the brain is neuroanatomy, while the study of its function is neuroscience. Numerous techniques are used to study the brain. Medical imaging technologies like functional neuroimaging, and electroencephalography (EEG) recordings are important in studying the brain. The medical history of people with a brain injury has provided insight into the function of each part of the brain.

Spinal cord injuries (SCIs) can range from mild concussion to severe laceration or compression of the spinal cord. SCIs are a major health problem, often resulting from motor vehicle accidents. The consequences of SCI depend on the type and level of injury, which are classified as tetraplegia (impairment below the cervical level affecting all four limbs), paraplegia (impairment below the thoracic, lumbar, or sacral regions affecting the trunk and legs), or hemiparalysis (impairment on one side of the body). Clinical manifestations include paralysis, loss of bladder/bowel control, loss of sweating below the neurologic level, and potentially life-threatening respiratory or cardiovascularCerebellum

The vestibular sensory organs of the inner ear responds to physical stimuli related to movement and orientation of the head in three-dimensional space. In response to mechanical forces acting on the inner ear, neural messages regarding head motion and position are generated by the vestibular apparatus and relayed to the brain. That information along with visual and proprioceptive input, is used by the central nervous system (CNS) to maintain clear vision during head movement, to control muscles responsible for upright posture and to provide a sense of orientation of the body with respect to the surrounding environment.
Although the vestibular system is one of our major sensory modalities, it differs somewhat from other senses such as vision and hearing in that it operates largely in the service of motor reflexes, outside the field of conscious perception. Thus we are not aware of vestibular sensory input unless the system is subjected to unusually high levels of stimulation or is compromised by disease, in which importance of vestibular function becomes acutely obvious. Some fundamental aspects of vestibular anatomy and physiology, emphasis on features of the system that provide the foundation for clinical testing of vestibular function.

During a routine dissection of a male cadaver, an anatomical variation was observed in the formation of the right median nerve. The median nerve was formed by four roots, with three roots originating from the lateral cord of the brachial plexus and one root from the medial cord. The four roots joined individually with the medial root to form the median nerve trunk in front of the third part of the axillary artery. However, the further distribution and arterial pattern in the arm was normal. This report discusses the rare occurrence of a median nerve formed by more than two roots and the potential clinical implications of such variations.More Related Content

This document reports on an anatomical variation found during a dissection of a male cadaver. Specifically, it describes the fusion of the lateral cord of the brachial plexus with the median nerve, and the absence of the musculocutaneous nerve, in the right upper limb. Normally the lateral cord would branch into the musculocutaneous nerve and lateral root of the median nerve. Here, the lateral cord fused with the median nerve proximal to the coracobrachialis muscle insertion. As a result, branches that would normally come from the musculocutaneous nerve instead originated from the median nerve. The cause of this variation may be related to errors in embryonic development of the nerves. Knowledge of suchHuman Reproductive system Physiology

The hypothalamus is a diencephalic structure located ventrally in the brain. It was first described by William His in 1893 and its connections to the posterior pituitary were described by Ramon y Cajal in 1894. It weighs around 4 grams and contains clustered nuclei with diffuse connections to other brain regions that allow it to integrate autonomic and endocrine functions with behavior such as regulating blood pressure, body temperature, energy metabolism, reproduction, and stress responses. The hypothalamus is divided into anterior, middle, and posterior regions containing various nuclei and plays an important role in visceral functions, brain functions, and generating circadian rhythms.Neuro-Anatomy of the Spinal Cord

The spinal cord extends from the foramen magnum to the L1-L2 vertebral level. It has 31 spinal segments and contains gray matter in an H-shaped cross-section. The spinal cord enlarges at the cervical and lumbar regions, corresponding to the brachial and lumbosacral plexuses. White matter tracts in the spinal cord include the posterior columns (gracilis and cuneatus), spinothalamic tracts, corticospinal tracts and spinocerebellar tracts. The meninges surrounding the spinal cord are the dura, arachnoid and pia mater. The cauda equina is formed from spinal nerve roots distal to the conusanatomy,physiology of spinal cord 7CSF

Non-Invasive ICP Monitoring for Neurosurgeons
Non-Invasive ICP Monitoring for NeurosurgeonsDhaval Shukla
油
This presentation delves into the latest advancements in non-invasive intracranial pressure (ICP) monitoring techniques, specifically tailored for neurosurgeons. It covers the importance of ICP monitoring in clinical practice, explores various non-invasive methods, and discusses their accuracy, reliability, and clinical applications. Attendees will gain insights into the benefits of non-invasive approaches over traditional invasive methods, including reduced risk of complications and improved patient outcomes. This comprehensive overview is designed to enhance the knowledge and skills of neurosurgeons in managing patients with neurological conditions.
Invasive systems are commonly used for monitoring intracranial pressure (ICP) in traumatic brain injury (TBI) and are considered the gold standard. The availability of invasive ICP monitoring is heterogeneous, and in low- and middle-income settings, these systems are not routinely employed due to high cost or limited accessibility. The aim of this presentation is to develop recommendations to guide monitoring and ICP-driven therapies in TBI using non-invasive ICP (nICP) systems.
