Describe the Structure of a Nerve

The central nervous system CNS contains the brain and the spinal cord. Describe the basic structure of a nerve.

Describe the structure of a nerve cell axon relative to a muscle fiber.

. It is also known as a neuron. Axons are long stem-like projections emerging out of the cell responsible for communicating with other cells called the Target cells thereby passing impulses. The dorsal root is also called the posterior or sensory root.

They are long so they. The axons are bundled together into groups called fascicles and each fascicle is wrapped in a layer of connective tissue called the perineurium. Nerve Structure Anatomy Nerves are the organs that make up the peripheral nervous system PNS.

The central nervous system is where we receive sensory information generate thoughts and emotions and store memories. It is also called as neuron. A nerve cell neuron consists of a large cell body and nerve fibersone elongated extension axon for sending impulses and usually many branches dendrites for receiving impulses.

The impulses from the axon cross a synapse the junction between two nerve cells to the dendrite of another cell. It is irregular in shape or polyhedral. The central nervous system and the peripheral nervous system.

The attachment of axon to the cell body of neuron is known as axon hillock. They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs. Inside the nerves groups of neurons nerve cells are organized into bundles called fascicles fasciculi.

View the full answer. This root conducts sensory impulses inward from the peripheral body parts. It contains tiny branches called dendrites all over the cell body.

It consist of cell body that contains nucleus and other cell organelles like mitochondria endoplasmic reticulum Golgi apparatus. Basically the nervous system is formed of nerve cells or neurons. It can be identified by the dorsal root ganglion.

Nerve cells or neurons are the structural and functional units of the nervous system. The nerve cell also known as a neuron is the main structural and functional unit of the nervous system. A long fibre axon which is insulated by a fatty myelin sheath.

Neuron Structure The neuron is the basic building block of the brain and central nervous system. Based on the structure of nerve cell axons and muscle fibers what function at the organism level do they work together to perform. The axons are long in length that starts to protrude out from the cell body of neuron.

It consists of three major parts namely Cell body dendrites Axon. The function of the axon is to carry signals away from the cell body to the terminal buttons in order to transmit electrical signals to other neurons. A nerve consists of many structures including axons glycocalyx endoneurial fluid endoneurium perineurium and epineurium.

Structure Of Nervous Tissue. The main part is the cell body which contains the nucleus cytoplasm and cell organelles. At the opposite end of the nerve cell body is the axon which is a long thin fiber with branches at the end that sends signals.

Neurons are specialized cells that transmit chemical and electrical signals. The 86 billion neurons in the nervous system work together to communicate wi. Nerve cell is the basic functional unit of the nervous system.

They transfer various messages from different parts of the body to the brain and back. Cord-like bundle of axons located in the peripheral nervous system that transmits sensory input and response output to and from the central nervous system. It contains cytoplasm and certain granular bodies called Nissles granules which contain a group of ribosomes for protein synthesis.

The axon is insulated by a myelin sheath made up of segments called Schwann cells. Use an example to support your answer. Branching off the nerve cell body are the dendrites which act like tiny antennae picking up signals from other cells.

The structure of the nervous system is divided into two main systems. Start studying Describe the structure of a nerve. Each spinal nerve emerges from the spinal cord by two short branches that lie within the vertebral column.

It is composed of a cell body that possesses a nucleus and remaining cell organelles like mitochondria endoplasmic reticulum Golgi apparatus. The axon also called a nerve fiber is a tail-like structure of the neuron which joins the cell body at a junction called the axon hillock. Neural tissue cell that is primarily responsible for generating and propagating electrical signals into within and out of the nervous system.

The impulses from the axon cross a synapse the junction between two nerve cells to the dendrite of another cell. It is made of nerve cells or neurons all of which consists of an axon. Sensory motor and relay.

It consists of tiny branches called dendrites all over the cell body. For a thorough knowledge of this system further works in anatomy physiology molecularbiology psychology medicine and other related fields are needed. There are three main types of neurone.

Learn vocabulary terms and more with flashcards games and other study tools. Leave a Reply Cancel reply. Even to-day thousands of scientists are involved in researches for knowing the structure and func-tioning of the brain.

Describe the structure of a spinal nerve. BYJUS Online learning Programs For K3 K10 K12 NEET. A nerve cell is the elementary functional unit of the nervous system.

A bundle of neurones is called a nerve. They are covered by a membrane known as axolemma. A nerve cell neuron consists of a large cell body and nerve fibersone elongated extension axon for sending impulses and usually many branches dendrites for receiving impulses.

The neurons or nerve cells are primarily involved in receiving and transmitting information from and to the brain. Describe the structure of a nerve the median nerve consists of bundles of nerve fibers imbedded in connective tissue and these bundles lie the nerve fibers imbedded among glial cells and protected by a myelin sheath.
