Answer #1

An afferent nerve fiber  is the axon of a sensory neuron in the peripheral nervous system that carry electrical signals (impulses) from receptors or sense organs to the central nervouse system. It  carry somatosensory information from the outside world, such as sensations of heat, cold, and pain, to the brain and spinal cord. It located in the ganglia of the peripheral nervous system, axons of these cells travel from ganglion to ganglion and lead back to the spinal cord. Damage to the afferent nerve fiber causes a wide range of symptoms like traumatic injuries can lead to peripheral neuropathy, which in turn can lead to things such as chronic liver disease, kidney disease, cancer, vitamin B deficiency etc.

55. Choose the false statement: A. When somatic motor nerve fibers innervate skeletal muscle tissues, each nerve cell extends the full distance from the CNS to the effector without synapsing along the way. B. During exercise, blood flow can be adjusted to match the demands of different skeletal muscles; here sympathetic fibers will increase blood flow (vasodilate) in the most active muscles, and parasympathetic fibers reduce flow (vasoconstrict) in less active muscles. C. During periods of stress, the adrenal medulla...
