What Neurotransmitters are released at the ends of some nerve cells?
An axon
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
Are nerves groups of cells that work together?
The nerve cells, or neurons, join together to make neural networks. These networks interact to form the whole of the nervous system.
Why are muscle cells round?
Muscle cells are not round. They are elongated and taper at the ends.
If its cells are striated and fused at the ends so that the cells contract as a unit then the tissue is what?
cardiac muscle.
What Neurotransmitters are released at the ends of some nerve cells?
An axon
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
When the blank reaches the ends of the axon the neurotransmitter is released and diffuses to the muscle cell membrane?
Synaptic vesicle
What term meaning to suture the ends of a severed nerve is?
Neurorrhaphy is surgical suture of the ends of a severed nerve.
What is the suturing of the ends of the severed nerve called?
Neurorrhaphy.
Is neurectomy the study of the ends of a severed nerve?
Neurectomy is surgical removal of a nerve
How does a single nerve impulse initiate many?
The nerve's endings are near to other nerve endings, when the potential of the potassium ion that is released is sensed by the other nerves they all might send an impulse to their other ends and the situation could be repeated.
How do neurons communicate with one another?
Neurons communicate by either chemical or electrical synapses. By far the predominant method is chemical though. The neuron releases a neurotransmitter like acetyl choline, glutamate, glycine and others to which the postsynaptic neuron or cell responds to. Synapses are the contact points where one neuron communicates with another. The dendrites are covered with synapses formed by the ends of axons from other neurons. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells.
What is the innervation of the forearm extensors?
The median nerve, supplies the lateral half of the arm, up to 1/2 of the fourth(ring) finger, while the ulnar nerve supplies the medial side of the arm, up to the pinky finger and the other 1/2 of the ring finger
Are nerves groups of cells that work together?
The nerve cells, or neurons, join together to make neural networks. These networks interact to form the whole of the nervous system.
What part of the neuron transmits messages to the muscles?
Afferent (sensory) division of the nerve cell receives input messages. The ends are called dendrites. A typical neuron in the central nervous system (CNS) has many thousand dendrites. It is the dendrites that receive the nervous signals from other neurons via connections called synapses.
What term describes suturing together the ends of a severed nerve?
neurorrhaphy
