The narrow space between the synaptic terminal and the muscle fiber is the?
synaptic cleft.
The actual gap between an axon ending and the muscle cell is called what?
Neuromuscular junction.
What is the difference between a dyad and triad in skeletal cardiac muscle?
In skeletal muscle, a triad is formed when a T-Tubule is flanked on either side by the calcium containing Terminal Cisternae of the Sarcoplasmic Reticulum, at the level of the Z-line. The intimate association of these three membranous sturctures (Terminal Cisternae---T-Tubule---Terminal Cisternae) for a Triad. This differs from a diad (or Dyad), in cardiac muscle where the T-Tubule is only intimately associated with ONE Terminal Cisternae.
What is the substance released at axon terminals?
The substance that is released at an axonal ending to propagate the nerve impulse to the next nerve or muscle is called
Gap between axon terminal and muscle cell?
The gap between the axon terminal and muscle cell is called the synaptic cleft. It is defined as the small gap, measured in nanometers, between an axon terminal and any of the cell membranes in the immediate vicinity.
What are functions of synaptic junction?
To "connect" two neurons, (or a neuron and a muscle cell), by providing a space between an axon terminal of one neuron and a dendrite of another neuron (or a muscle cell), so neurotransmitters that are released by an axon terminal can diffuse across that space to reach the dendrite (or muscle cell) and either initiate the possibility of the second neuron to fire or cause a muscle cell to contract.
Where are the cross bridges involved in muscle contraction?
in the terminal cisternae
What is axonal recruitment?
Axonal recruitment refers to the process by which an increasing number of axons in a nerve are activated to generate a stronger neural signal or action potential. Each axon is capable of generating an action potential, which is an electrical signal that travels along the length of the axon. However, at low levels of stimulation, only a subset of axons in a nerve will generate action potentials. As the level of stimulation increases, more axons will begin to generate action potentials, leading to increased neural activity. Axonal recruitment is an important mechanism for regulating the strength and sensitivity of neural signals. It allows the nervous system to modulate the strength of its responses to different levels of stimuli, and can be observed in a variety of physiological processes, including muscle contraction and sensory processing.

The triads of a muscle fiber consist of?
Two terminal cisternae and a T-tubule
Where are the calcium ions stored in the muscle cells?
terminal cisternae of the sarcoplasmic reticulum
What is the function of the neuromuscular junction is to?
Includes the axon terminal of a motor neuron plus the motor end plate of a muscle fiber. Is where the axons of motor nerves meet the muscle & transmit messages from the brain which cause the muscle to contract & relax.
The skeletal muscle complex known as the triad consists of what?
one transverse tubule and two terminal cisternae
