The autonomic reflex contains two. (preganglionic and postganglionic)
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.
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.
Action potential
neurons
Axon hillocks
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.
The key factors that influence the generation and propagation of action potential in neurons are the balance of ions inside and outside the cell, the opening and closing of ion channels, and the threshold level of stimulation needed to trigger an action potential.
The action potential increases slightly because more neurons are being stimulated.
Yes, the action potential is an all-or-nothing response in neurons, meaning that once a certain threshold is reached, the neuron will fire at full strength regardless of the strength of the stimulus.
Disturbances to sensory neurons can cause depolarization of the neuron's membrane, reaching a threshold that triggers an action potential. This action potential then travels along the neuron's axon to the central nervous system, where it is processed and interpreted as a sensory experience.
TRUE. Neurons with myelin (or myelinated neurons) conduct impulses much faster than those without myelin.
