Is an ankle jerk reflex somatic or autonomic?
Ankle jerk is somatic. It is the reflex action, in which the afferent. connecting and the efferent neurons are involved. Autonomic nerves do not supply the striated muscles.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Which cell conducts an action potential?
neurons
Why are motor neurons also known as efferent neurons?
efferent neurons are just another name for motor neurons, indicating that they carry impulses from the brain (CNS) to the target cell. Similarly, the term 'afferent''can be used interchangeably with sensory as it describes the action of a neuron carrying impulses from the stimulis (which could either be internal or external) to the CNS.
Movement of arms and legs what major neurotransmitter involved?
Skeletal muscles move via action potential that is conducted by axons to the neuromuscular junction and across the synaptic gaps of efferent motor neurons. The main neurotransmitter responsible for this job is acetylcholine.
Why is the action potential generated in neurons only?
may be there are specific arrangement of sodium and potassium ion channels in neurons which is not found in any other cell andthis arrangement is necessary for action potential generation but i am ot sure what kind of arrangement is needed for action potential generation and what kind is presentr in neurons and other cells .
What is usually the sites of the initial action potential in neurons?
Axon hillocks
What transfers a signal from the afferent nerve to the efferent nerve?
Neurotransmitters are released from the terminal bouton of the afferent nerve, cross the synaptic cleft, and bind with receptors on the efferent nerve. If enough neurotranmitter binds to reach the minimum potential, an action potential is created and the signal moves down the efferent nerve.
Why does the nerve action potential increase slightly when you add 1.0 V to the threshold voltage and stimulate nerve?
The action potential increases slightly because more neurons are being stimulated.
Disturbances when will sensory neurons result in an action potential?
if the graded potential of threshold size reaches a trigger zone
What is an afferent neuron?
Afferent neurons are those that transmit signals from sensory transducers to the central nervous system (i.e., the spinal cord and the brain). The complementary group of neurons are the efferent neurons that transmit signals from the central nervous system to effectors, that generate a response to the environmental input.
Do action potential transmission is faster in myelinated neurons?
TRUE. Neurons with myelin (or myelinated neurons) conduct impulses much faster than those without myelin.
