Question

the slowdown of neural communication in multiple sclerosis involves a * 2 points
thresholds
dendrites
myelin sheath
endocrine gland
as you are reading this question, the cells in your eyes are firing in response to the light coming from this computer. which type of neuron is carrying this message to the brain? * 2 points
efferent
sensory
interneuron
motor

Explanation:

1. In multiple sclerosis, the myelin sheath that insulates nerve fibers degenerates, leading to a slow - down of neural communication. Dendrites receive signals, thresholds are related to action potential initiation, and endocrine glands secrete hormones not related to this neural - communication issue.
2. Sensory neurons carry information from sensory receptors (like in the eyes) to the brain in response to stimuli (such as light from the computer screen). Efferent neurons carry signals from the brain to effectors, interneurons are in the central nervous system for signal processing, and motor neurons are related to muscle movement.

Answer:

1. myelin sheath
2. sensory
