The components of the nervous system that are involved in the physical sensation is the peripheral nervous system, which is divided into two groups they are, sensory and motor divisions. The sensory impulse moves through the body by stimulating a receptor in the skin, and it goes through the sensory neurons and also travels through the afferent fibers, the spinal cord and also into the brain.
2. What components of the nervous system are involved in skeletal muscle movement? How does motor impulse move throughout the body? What is a “motor unit”?
The components of the nervous system involved in the skeletal muscle movement is the motor division. The motor impulse moves through the body by traveling through efferent fibers. A motor unit is a neuron and also that is where all the other muscle fibers are connected.
3. What movements are involved in the action of standing up? What muscles need to contract to perform these actions?
The movements involved in the action of standing up is when the muscles contracting. The muscles that are needed to perform these actions are the glutes, hamstrings, and the quadriceps.
