What are the two ways by which the nervous system can control the force generated by a muscle?

The central nervous system has two distinct ways of controlling the force produced by a muscle through motor unit recruitment: spatial recruitment and temporal recruitment. Spatial recruitment is the activation of more motor units to produce a greater force.

What is the point of communication between the nervous system and muscle?

The site where motor neurons and muscle cells communicate with each other is called the neuromuscular junction. This is where the neurons transfer signal substances that can be taken up by the muscle cells to make them contract.

Where does communication between the nervous system and skeletal muscle happen?

Muscle and nerve communicate at the level of a specialized region, namely the neuromuscular junction (NMJ), a synaptic connection where the peripheral nervous system contacts skeletal muscle fibers, governing crucial vital processes, such as body voluntary movements and breathing [1].

What are the two components that specifically interact to enable muscle contraction?

Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of myosin to actin filaments, allowing myosin to function as a motor that drives filament sliding.

Which nervous system controls muscles?

The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles.

What is contraction and relaxation?

Muscle contraction is the activation of tension-generating sites within muscle cells. ... The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.

What is the relationship between nerves and muscles?

Your nervous system (brain and nerves) sends a message to activate your skeletal (voluntary) muscles. Your muscle fibers contract (tense up) in response to the message. When the muscle activates or bunches up, it pulls on the tendon. Tendons attach muscles to bones.

How the nervous system communicates?

Nerves carry lightning-fast electrical messages up and down the spinal cord. Messages travel from the brain into the spinal cord and out to the body's nerves to tell the body what to do. Messages to the brain tell it what's happening with the rest of the body.

How the communication takes place between brain and different part of the body?

Your brain is made up of billions of cells called neurons. Your neurons carry information in the form of electrical pulses. Neurons communicate with each other and the rest of your body at special meeting points called synapses.

How does a neuron communicate with a muscle cell?

Neuron action potentials cause the release of neurotransmitters from the synaptic terminal into the synaptic cleft, where they can then diffuse across the synaptic cleft and bind to a receptor molecule on the motor end plate.

How do muscle cells communicate?

Cellular communication is mediated by lipids, fusogenic membrane proteins, and exosomes. Muscle-derived exosomes carry proteins and micro RNAs as cargo. Secreted factors such as IGF-1, TGFβ, and myostatin are also released by muscle cells providing local signaling cues to modulate muscle fusion and regeneration.

What is the relationship between the motor neurons and muscle fibers?

Thus, there is a one-to-one relationship between a muscle and a motor neuron pool. Each individual muscle fiber in a muscle is innervated by one, and only one, motor neuron (make sure you understand the difference between a muscle and a muscle fiber). A single motor neuron, however, can innervate many muscle fibers.

How do isotonic and isometric contractions differ?

2 What is the difference between isometric and isotonic exercise? Isotonic muscle contraction produces limb movement without a change in muscle tension, whereas isometric muscle contraction produces muscle tension without a change in limb movement.

What stimulates muscles to contract?

A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.

Which occurs during muscle contraction?

Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. ... In this conformation the cross-bridge binds weakly to actin and attaches and detaches so rapidly that it can slip from actin site to actin site, offering very little resistance to stretch.
