The nervous system is made up of the brain, spinal cord and nerves. It controls everything by receiving messages from nerves and giving instructions back to the nerves. The nerves are connected to the brain by the spinal cord which allows communication between the brain and the rest of the body.

The nervous system is the body's control and communication system that regulates all bodily functions. It has two main parts - the central nervous system consisting of the brain and spinal cord, and the peripheral nervous system made up of nerves outside the brain and spinal cord. The nervous system contains neurons, or nerve cells, which receive and transmit electrochemical signals, as well as neuroglial cells that support and protect neurons. The neuron is the basic structural and functional unit of the nervous system.Chapter 12

The document summarizes the main components and functions of the nervous system in three parts. The central nervous system consists of the brain and spinal cord and processes sensory and motor messages. The peripheral nervous system includes cranial and spinal nerves and carries information between the central nervous system and other body parts. Nervous tissue contains neurons and neuroglial cells that transmit electrical signals and support neuronal functions respectively.Central Nervous system CNS

The central nervous system (CNS) consists of the brain and spinal cord. The CNS is protected by three layers of tissue called meninges and surrounded by cerebrospinal fluid. It contains four interconnected ventricles that produce cerebrospinal fluid. The brain is divided into the forebrain, midbrain, and hindbrain. The forebrain contains the cerebrum and limbic system. The cerebrum is made up of grey matter and white matter and is involved in voluntary movement and complex functions. The spinal cord carries signals between the brain and body and contains 31 pairs of spinal nerves.Nervous system

This document discusses the nervous system, which connects all parts of the body and transmits signals. It has two major divisions: the central nervous system (CNS) and peripheral nervous system (PNS). The CNS includes the brain and spinal cord, and serves as the main processing center. The PNS connects the CNS to organs and limbs, and has two divisions - the somatic nervous system for voluntary movement, and autonomic nervous system for involuntary functions like breathing.Nervous system

The document discusses the nervous system, including:
- It is divided into the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) connecting to the CNS.
- The CNS contains over 1 trillion neurons and quadrillions of connections, and is responsible for functions like perception, movement, and cognition.
- The brain is the control center and is divided into the cerebrum, cerebellum, and brain stem, each with distinct functions like learning, coordination, and regulating vital functions.
- The spinal cord transmits signals between the brain and body and coordinates reflexes through ascending and descending tracts.The nervous system

The document discusses the nervous system and its main components:
1) The central nervous system (CNS) controls most body functions and consists of the brain and spinal cord. The brain interprets sensory information and controls movement.
2) The peripheral nervous system (PNS) connects the CNS to organs and limbs. It has two divisions - the somatic nervous system which controls voluntary movement, and the autonomic nervous system which controls involuntary functions.
3) Nerve fibers transmit signals in the CNS and PNS. Myelin sheaths surround some fibers and are formed by different cells in each system.Minersville HS Applied Anatomy Nervous System

Neurons are specialized cells that communicate via electrical and chemical signals. They consist of a cell body containing the nucleus, along with dendrites that receive signals and a long axon that transmits signals. There are three main types: sensory neurons transmit signals to the central nervous system, motor neurons transmit signals from the CNS to effectors, and interneurons connect sensory and motor neurons within the CNS. The simplest nerve pathway is a reflex arc involving receptors, sensory neurons, interneurons, motor neurons and effectors. The central nervous system coordinates information and consists of the brain and spinal cord. The peripheral nervous system connects the CNS to organs and consists of cranial and spinal nerves.Nervous system

The insect nervous system consists of three main parts: the central nervous system (CNS), the visceral nervous system, and the peripheral nervous system. The CNS contains a brain and a ventral nerve cord made up of fused ganglia. It receives and processes sensory information. The visceral nervous system innervates internal organs. The peripheral nervous system connects the CNS and visceral nervous system to muscles and sense organs via motor and sensory neurons. Together these systems allow insects to respond to their environment and control bodily functions through neural pathways and chemical signaling between different neuron types.Nervous system ppt

The nervous system is made up of neurons that transmit signals between different parts of the body through fibers called axons and chemicals called neurotransmitters. There are two main types of neurons - sensory neurons that respond to stimuli, and motor neurons that carry signals to muscles and glands. The nervous system is divided into the central nervous system, made up of the brain and spinal cord, and the peripheral nervous system with nerves connecting the CNS to the rest of the body. The nervous system controls both voluntary functions through the somatic system and involuntary functions like breathing through the autonomic system. Common nervous system disorders include epilepsy, Parkinson's disease, multiple sclerosis, ALS, and Alzheimer's disease.Ficha picasso

The digestive system helps break down food and absorb nutrients. It includes the mouth, which breaks food into pieces using teeth. Food then moves to the stomach through the esophagus. In the stomach, gastric juices break food down further into a liquid over 3 hours. This liquid passes into the small intestine, where nutrients are absorbed into the bloodstream. Waste then moves to the large intestine and exits the body through the anus.THE EXCRETORY SYSTEM

The document discusses the key differences between living and non-living things. It notes that living things such as animals, plants and fungi need food, water and air to survive. They are also born, grow, reproduce and die. The three main life processes for all living things are nutrition, interaction and reproduction. Several examples are provided to illustrate these concepts, such as a hen laying an egg to reproduce or a squirrel eating a pinecone for nutrition.Recently uploaded (20)
