The muscle responds and pulls on a bone by way of a tendon. It can not react until the nerve tells it to.

∙ 15y agoA nerve impulse is technically referred to an action potential (AP). When an AP occurs, a tiny electrical current travels from one end of the neuron to the other in the direction away from the cell body. Once it reaches the end, which forms a part of the synapse called the presynaptic axon terminal, the neuron's neurotransmitters are released. From here they will diffuse a very short distance and make contact with receptors located on a postsynaptic cell dendrite. What happens next depends on the neurotransmitter that was released and the receptor it binds to, and how many are bound. The next cell could fire an action potential too - or it may become less active

∙ 14y agoBANG! The muscle contracts and action appears in front of your eyesLOL!
It should be noted, too, that when a muscle cell is innervated, that cell contracts at maximum. So, when one wants to exert anything less than maximal strength, only the number of fibres necessary to elicit the action to the degree that your mind instructs do so.

When a muscle receives a nerve signal it and pulls on a tendon?
The muscle responds and pulls on a bone by way of a tendon. It can not react until the nerve tells it to.
When muscle receives a nerve signal it blank and pulls on a tendon?
The muscle responds and pulls on a bone by way of a tendon. It can not react until the nerve tells it to.
Which Nerve ending is located in a tendon and protects against overcontracting?
The internal tendon bulk is thought to contain no nerve fibres, but the epitenon and paratenon contain nerve endings, while Golgi tendon organs are present at the junction between tendon and muscle.
What happens when a nerve does not signal a muscle?
the muscle doesn't move
Does each muscle in a limb receives its nerve supply from one spinal nerve?
False
Diaphragm contractions are regulated by what nerve?
The diaphragm's contractions are regulated by the phrenic nerve. A diaphragm are the muscle that inserts on the central tendon.
What muscle or gland cell receives nerve impulses?
I believe it is the Neuron?
What are the effector muscles involved in a knee-jerk?
Gastrocnemius muscles is the effector. Afferent Nerve- Sciatic Efferent Nerve- Sacral 1 & 2 Nerve roots Receptors- Tendon nociceptors in Tendon of Achilles Integration centers- Interneurons in the spinal cord
Which substance is stored in the muscle's endoplasmic reticulum and then released when a nerve signal stimulates a muscle fiber?
Calcium ions
What is a Golgi tendon organ?
True
What nerve ending responds to cold?
It's the encapsulated endings- nerves that are found in the skin and joint capsules (end bulb of Krause, Ruffini corpuscles, Meissner's corpuscles, Pacinian corpuscles); skeletal muscle (neuromuscular spindles); muscle-tendon junctions (Golgi tendon organ)
What usually triggers muscle fibers to contract or relax?
The contraction is triggered by the release of calcium within the muscle which is triggered by an electrical signal from a nerve.
