- The nervous system can be divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and spinal cord, while the peripheral nervous system consists of sensory and motor nervous cells that run throughout the rest of the body.Neurons are responsible for sending, receiving, and interpreting information from all parts of the body. neuron consists of two major parts: Axons and dendrites are bundled together into what are called nerves. These nerves send signals between the brain, spinal cord, and other body organs via nerve impulses. Nerve impulses are received at the neuronal dendrites and are carried along the axon to the terminal branches.

What are the parts of the nervous system? The brain sends messages through the spinal cord and nerves of the peripheral nervous system to control the movement of the muscles and the function of internal organs. The basic working unit of the nervous system is a cell called a neuron. The human brain contains about 100 billion neurons. A neuron consists of a cell body containing the nucleus, and special extensions called axons (pronounced AK-sonz) and dendrites (pronounced DEN-drahytz).

- The spinal ganglia or dorsal root ganglia contain the cell bodies of sensory neurons entering the cord at that region. nerve-a group of fibers (axons) outside the CNS. The spinal nerves contain the fibers of the sensory and motor neurons.A nerve does not contain cell bodies.They are located in the ganglion (sensory) or in the gray matter (motor). tract-a group of fibers inside the CNS. The spinal tracts carry information up or down the spinal cord, to or from the brain.n the spinal cord the synapses between sensory and motor and interneurons occurs in the gray matter. The cell bodies of the interneurons and motor neurons also are found in the gray matter. white matter-an area of myelinated fiber tracts. Myelination in the CNS differs from that in nerves.

Spinal cord The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS).or the nerves of the lower spinal cord, this means that they exit the vertebral column much lower (more caudally) than their roots. As these nerves travel from their respective roots to their point of exit from the vertebral column, the nerves of the lower spinal segments form a bundle called the cauda equina.

Central Nervous System Function Neurons are the basic unit of the nervous system. All cells of the nervous system are comprised of neurons. Neurons contain nerve processes which are finger-like projections that extend from the nerve cell body. The nerve processes consist of axons and dendrites which are able to conduct and transmit signals.

Nervous system The nervous system derives its name from nerves, which are cylindrical bundles of fibers (the axons of neurons), that emanate from the brain and spinal cord, and branch repeatedly to innervate every part of the body.t the cellular level, the nervous system is defined by the presence of a special type of cell, called the neuron, also known as a nerve cell. Neurons have special structures that allow them to send signals rapidly and precisely to other cells.

How Your Brain Works 1 Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system. 2  Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body.  Interneurons connect various neurons within the brain and spinal cord.

Central Nervous System Function Neurons are the basic unit of the nervous system. All cells of the nervous system are comprised of neurons. Neurons contain nerve processes which are finger-like projections that extend from the nerve cell body. The nerve processes consist of axons and dendrites which are able to conduct and transmit signals.Axons typically carry signals away from the cell body.he nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body.

- Millions of messengers. Your nervous system contains millions of nerve cells, called neurons. Neurons are highly specialised to transmit messages from one part of your body to another. All neurons have a cell body and one or more fibres. These fibres vary in length from microscopic to over 1 metre.

Overview Major divisions of the peripheral nervous system. Nerve cells are called neurones. A neurone consists of a cell body (with a nucleus and cytoplasm), dendrites that carry electrical impulses to the cell, and a long axon that carries the impulses away from the cell.

Anatomy of the Brain The peripheral nervous system (PNS) is composed of spinal nerves that branch from the spinal cord and cranial nerves that branch from the brain. The PNS includes the autonomic nervous system, which controls vital functions such as breathing, digestion, heart rate, and secretion of hormones.

Cranial Nerves - Anatomy & Physiology Many of the cranial nerves with nuclei within the brain stem contain sensory and motor neurone components. The sensory fibre components have their cell bodies located in ganglia outside the central nervous system and the motor fibre element have their cell bodies within the central nervous system.he glossopharyngeal nerve is part of the group of cranial nerves responsible for innervation of structures derived from the branchial arches. This nerve innervates structures related to the third branchial arch.
