Explanation:
The neuron is part of the somatosensory pathway
The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.
The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.
Somatosensory pathways contain primary, secondary, and tertiary neurons which are capable of processing information about vibration, touch, temperature, and pain- information is passed on after receiving stimuli from the body's internal or skin receptors. Thus the precision is greater in the lips and fingers (directly involved in tactile interactions with stimuli) than on the back.

Cells differentiate in order to create cells that perform specific functions.
Answer:
Lower limbs are larger in size as compared to upper limbs.
Explanation:
The size of the upper and lower extremities of the appendicular skeleton is different from one another due to their difference in size. Lower limbs are larger in size as compared to upper limbs due to their difference in functions. The function of the upper and lower extremities of the appendicular skeleton also different from one another. The function of upper limbs to grasp and manipulate objects while on the other hand, the lower limbs allows the person in locomotion.
<span>simple answer - it is a non-polar layer. so polar molecules are not able to pass through it easily. they need to be actively or passively transported across. non-polar molecules are able to just move through.</span>
