What is the function of nodes of Ranvier? What is the function of chemoreceptors? What functional advantage does a neuron with several dendrites have? What are autonomic functions? How is a neuron adapted to its function? What are the functions of the nodes of Ranvier?
When internal or external stimuli converge on the body, motor neurons have the ability to trigger the muscles to contract or relax. This immediate reaction is the reason why the body has the ability to move and adapt to changes. Injury or damage to either the afferent or efferent neuron netw...
Amyotrophic lateral sclerosis is characterized by upper (UMN) and lower motor neuron (LMN) degeneration which negatively impacts the ability of respiratory and laryngeal musculature to work in harmony during the cough phases. The rigidity due to UMN degeneration and weakness due to LMN degeneration ...
The neuron that released the neurotransmitters will reabsorb and recycle them. Why it’s important to maintain healthy neurotransmitter activity Since neurotransmitters play such a vital role in everything we do, it's important to follow a lifestyle that keeps these messengers in tip-top shape. ...
Free Essay: A neuromuscular junction is a chemical conjunction formed during the contact between motor neuron and a muscle fiber. Each branch of a motoneuron...
A retinal ganglion cell is a neuron in the mammalian retina that receives input from both bipolar and amacrine cells. The way...
An action potential refers to the changing neuronal plasma membrane potential when sodium ions flow into the neuron and potassium ions flow out. This corresponds to rapid depolarisation and then repolarisation.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try...
It is significant for the recovery from injuries or diseases within thenervous system. STRUCTURE OF NERVES Nerve cells, also known asneurons, form the building blocks of nerves. Each neuron comprises a cell body, dendrites, and an axon. ...
In the motor neuron, substances have to move across the membrane to ensure the correct functioning of the nervous system. How is the movement of Na/K different from the movement of neurotransmitters across a plasma membrane? In the ...
What is a granular layer? Medical Definition of granular layer : the deeper layer of the cortex of the cerebellum containing numerous small closely packed cells. Where are pyramidal cells found? A common class of neuron found in the cerebral cortex of virtually every mammal, as well as in bir...
