Wearing on Her Nerves: Exploring the Interrelation between the Nervous and Muscular Systems
1) The peripheral nervous system (PNS). First by being stimulated by a receptor in the skin, which goes to the sensory neurons and travel through afferent fibers, then through the spinal cord and finally to the brain.
2) The motor division. Motor impulses travel through efferent fibers. A motor neuron and all the muscle fibers connected to it.
3) Muscles contracting. Glutes, hamstrings, and quadriceps
4) Muscle, fascicle, muscle fiber, myofibril, myofilament. -The smallest contractile unit of muscle; the proteins slide past each other when the muscles relax and contract. 5) It binds to the receptors on the motor end plate, which causes the electric potential that causes the plate to change and initiates an action that passes in both directions along the muscle fibers. After the tubules on the muscle fiber surface open, the action potential spreads inside the muscle fiber. Calcium ions are then released at each point where the tubules touch the sarcoplasmic reticulum.
- When the specific enzyme acetyl cholinesterase breaks down acetylcholine.
6) Both
7) Layer of proteins and fatty acids surrounding nerves, and allows impulses to travel more quickly.
-Glial cells.
8) Thickening or hardening of a body part; brain and/or spinal cord.
-The brain becomes unable to send and receive messages.
9) It uses an imaging processor that
