What kind of stimulus travels from the motor neuron to skeletal muscle?
The stimulus that travels from the motor neuron to skeletal muscle is an electrical signal called an action potential. This action potential causes the release of neurotransmitters, specifically acetylcholine, which then stimulates muscle contraction.
What ist the process called that causes the cell to contract or shorten?
This process is called contraction. Muscles shorten or contract to produce movement.
What neurotransmitter causes muscle movement?
Acetylcholine is the primary neurotransmitter responsible for muscle movement. It is released from motor neurons at the neuromuscular junction to stimulate muscle contraction.
What movement of the thigh does contraction of the gluteus maximus produce?
Contractions of the gluteus maximus muscle causes (hyper)extension of the thigh.
What is an example to illustrate anatomy vs physiology?
A good example to illustrate the relationship between anatomy and physiology is the relationship between how a skeletal muscle is structured (anatomy) and how it works (physiology) to produce a muscle contraction. Skeletal muscles are organized into units called sarcomeres which are overlapping chains of two different proteins, actin and myosin. That in a nutshell is the microscopic anatomy of skeletal muscle. Physiologically how it works is that the myosin heads latch onto the actin chain pulling it into the center of the sarcomere shortening it which causes the contraction.
What causes lymph to move toward the heart?
The lymph is circulated via muscle movement. The lymphatic system is not closed and has no central pump; thus transport is slow and sporadic. Lymph movement occurs due to peristalsis (propulsion of the lymph due to alternate contraction and relaxation of smooth muscle), valves, and compression during contraction of adjacent skeletal muscle and arterial pulsation.
How does the skeletal system and the nervous system work with each other?
the connection between the two is like this. the nervous system sends the signal to the skeletal muscle to contract. This contraction causes the muscle to pull the bone, and the bone bends. This would mean that the movement of the skeleton is caused by nervous system which triggers the skeletal muscle to move the skeleton.
What type of muscle causes voluntary movement?
Striated (or skeletal) muscle
What is a principal character in a literary work also a muscle which causes movement through contraction?
agonist
What is an agonist muscle?
Agonist is a classification used to describe a muscle which causes specific movement or several movements through the process of contraction. This is a term for skeletal muscles, usually. Agonists are also sometimes called "prime movers" since they are the muscles being considered that are primarily responsible for generating a specific movement.
What causes the movement of lymph through lymphatic vessels?
The movement of lymph through lymphatic vessels is caused mostly by movement, however lymph pressure also plays a part.
What tissue is attached to bone that causes movement?
Muscle Tissue
What ist the process called that causes the cell to contract or shorten?
This process is called contraction. Muscles shorten or contract to produce movement.

What movement of the thigh does contraction of the gluteus maximus produce?
Contractions of the gluteus maximus muscle causes (hyper)extension of the thigh.
What causes the creep mass movement?
Creep mass movement is caused by the slow downhill movement of soil or rock due to gravity, soil expansion and contraction, or freeze-thaw cycles. Over time, this movement can result in the displacement of materials downslope.
