Which cells from the anterior gray horn are the only ones that terminate in skeletal muscle cells?
Axons from the anterior gray horn are the only ones that terminate in skeletal muscle cells. This principle of the final common path to skeletal muscles has important practical implications.
Are sodium and potassium the final go signal in muscle contraction?
an increase in intracellular calcium ion levels
What is the connective tissue membrane that covers skeletal muscles?
This is the fascia, which is actually composed of three separate levels. There is one layer that wraps around each muscle fiber, another layer that wraps around each muscle bundle and then a final layer that wraps around the whole muscle.
Chemical released to stimulate muscle contraction?
Acetylcholine is the primary neurotransmitter released by motor neurons at the neuromuscular junction to stimulate muscle contraction. It binds to receptors on the muscle cell membrane, initiating a series of events that ultimately lead to muscle contraction.
What is principle of final common path?
The principle of the final common path is:Only one final common path (namely, each single motor neuron from the anterior gray horn of the spinal cord) conducts impulses to a specific motor unit within a skeletal muscle.
What causes heart muscle to contract?
Nerve impulses that originate in the central nervous system cause muscles to contract. Muscle fiber generates tension during the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same.

Who is typically involved in the third or final stage of economic development?
big companies

Why are lower motor neurons referred as the finals pathway?
Lower motor neurons are referred to as the final pathway because they are the last stage in the neural circuitry that conveys motor commands from the central nervous system to the muscles. They directly innervate the muscles and are responsible for initiating muscle contraction and generating movement.
Who was involved when the Civil War ended?
General Ulysses Grant and General Robert E. Lee were involved in the final battle of the Civil War.
A multicellular organism characterized by muscle and nervous tissue and undergoes development to achieve its final form?
animal
