Pseudounipolar cells (example: dorsal root ganglion cells). Actually, these cells have 2 axons rather than an axon and dendrite. One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle. Multipolar neurons have many processes that extend from the cell body. However, each neuron has only one axon

These two parts of the cell are responsible for relaying electrical signals with other nerve cells. (iii) Bipolar: Axon and dendrite emerge. from the opposite ends of soma (iv) Multipolar: One axon and many den- In most respects, neurons are like other body cells, Download 1,473 Axon Dendrite Stock Illustrations, Vectors & Clipart for FREE or amazingly low rates!

C. cell body. D. myelin sheath. Use the following diagram for the next 2 questions 3. If molecule X causes depolarization at Y, what could X be? A. sodium ions B. calcium ions C. acetylcholine D. acetylcholinesterase 4. This diagram illustrates how sensory neurons carry nerve impulses from sensory receptors towards the central nervous system, and motor neurons carry impulses away from the CNS towards the effectors (muscles and glands). Notice that sensory and motor neurons look a bit different, and the cell body of each one is found in a slightly different location Question 1 What part of the neuron carries impulses AWAY from the cell body?

Solution : The nervous is made up of specialized cells called nerve cells or neurons. A neurons have three parts; cell body(soma/ cyton), Axon, Dendrite. Axons

(i) Dendrite (ii) Cell body (iii) Nucleus (iv) Axon (b) Name the parts of a neuron : (i) where information is acquired (ii) through which information travels as an electrical impulse (iii) where this impulse must be converted into a chemical signal for onward transmission (c) Define neuromuscular junction. During the development of dendrites, several factors can influence differentiation. These include modulation of sensory input, environmental pollutants, body temperature, and drug use.

Draw and label a myelinated neuron showing the cell body, dendrite, axon, axon terminal, Schwann cells and Nodes of Ranvier. Provide a brief description of the function of each labeled structure beside its label. Please be neat! cell body = performs housekeeping functions of the cell . dendrite = receives chemical signals from other

The signals go into the cell body (or soma). A cell may have hundreds of dendrites, but may have only one axon. The dendrites carry signals from other neurons into the soma, and the axon carries a single signal from the soma to the next neuron or to a muscle fiber.

dendrite = receives chemical signals from other Dendrite is a short branched extension of a nerve cell, along which impulses received from other … Cell body. Each nerve cell (neuron) has a cell body with many different branches extending from it. Dendrite. Many spider-like arms branch from the cell body. These are called dendrites, and they carry incoming messages to the cell. Axon. An axon is a long, thin fibre that extends from the nerve cell body.

SURVEY . 30 seconds . An axon (from Greek ἄξων áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body.The function of the axon is to transmit information to different neurons, muscles, and glands.

All neurons have three main parts: 1) dendrites, 2) cell body or soma, and 3) axons. Besides the three major parts, there is the presence of axon terminal and synapse at the end of the neuron. Bipolar neurons have two processes extending from the cell body (examples: retinal cells, olfactory epithelium cells). Pseudounipolar cells (example: dorsal root ganglion cells). Actually, these cells have 2 axons rather than an axon and dendrite. One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle.
