The correct answer is: B) nodes of Ranvier.
Schwann cells are non-neural cells that are part of the peripheral nervous system with supportive function for neurons. In myelinated axons, Schwann cells form the myelin sheath that is not continuous. The tiny gaps between adjacent Schwann cells are called nodes of Ranvier.
Nodes of Ranvier are the spots where the axolemma (the cell membrane of an axon) is exposed to the extracellular space. Because of the presence of nodes, nerve conduction in myelinated axons is referred to as saltatory conduction.
Answer:yes
Explanation:scientific method
Feature detection is a process by which the nervous system sorts or filters complex natural stimuli in order for it to extract behaviorally relevant cues that has been so high. one example is the external skeleton. an external skeleton, also known as the exoskeleton, this is an external covering that supports and protects the body of an animal.
The answer is true. Melatonin is a hormone that is created by the pineal
gland<span> in animals and controls sleep and alertness. It<span> seems
to have 2 possible interacting effects on the sleep-wake cycle. First, it encourages
sleep and stability in a “hypnotic” function by escalating the homeostatic coerce
to sleep. Second, it entrains and modifies the process c in a “chronobiotic”
function.</span></span>
