Is it true Skeletal muscle contraction causes ATP to break down releasing heat that is distributed about the body?
Yes, during skeletal muscle contraction, ATP is broken down to provide the energy needed for muscle fibers to contract. This process generates heat as a byproduct, contributing to thermoregulation in the body. The heat produced is then distributed throughout the body, helping to maintain a stable internal temperature.

What type of muscle is capable of rapid contraction and causes skeletal movement?
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
Which object forms by the contraction of a large sphere of gases causing the nuclear fusion of lighter elements into heavier elements?
A star forms by the contraction of a large sphere of gases. This contraction causes the nuclear fusion of lighter elements into heavier elements, releasing energy in the process.
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.
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 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.
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.
A contraction that causes a muscle to lengthen rather than shorten is called?
An eccentric contraction is one that causes a muscle to lengthen.
The action potential is conducted into a skeletal muscle fiber by?
The action potential is conducted into a skeletal muscle fiber by the depolarization of the motor end plate, which triggers the opening of voltage-gated sodium channels. This causes an influx of sodium ions into the muscle fiber, leading to depolarization and the initiation of muscle contraction.
Contraction mechanism in a skeletal muscle cell?
ACH is released at the end-plate potential. ACH diffuses into the sarcolemma, attaches to the receptors in the motor end plate and causes a change in the ions permeability that creates graded depolarization of the end-plate potential. Basically, it attaches to the receptors in the motor-end plate and creates the beginning process of triggering muscle contractions.
What causes damage to the skeletal system?
A fall or trama.
What are the causes of releasing semen?
wet dreams
What causes bp to fluctuate?
due to contraction of heart
