The sites where a chemical substance is transmitted from the presynaptic terminal of an axon to the postsynaptic membrane of a muscle fiber are called?
The sites where a chemical substance is transmitted from the presynaptic terminal of an axon to the postsynaptic membrane of a muscle fiber are called neuromuscular junctions. At these junctions, the neurotransmitter acetylcholine is released from the presynaptic terminal and binds to receptors on the postsynaptic membrane, initiating muscle contraction.
What is the narrow space that separates the motor neuron and the skeletal muscle fiber in a neuromuscular junction called?
Neuromuscular junction or neuromuscular synapse
Are cell junctions found between plant cells only?
No, cell junctions are also found between animal cells. In plants, cell junctions are called plasmodesmata, while in animals they are called tight junctions, gap junctions, and desmosomes. These structures facilitate cell-to-cell communication and adhesion.
What is a group that is closer together than the surrounding stars is called an?
A group of stars that are closer together than the surrounding stars is called a star cluster. Star clusters can be divided into two main types: open clusters and globular clusters, with open clusters being more loosely bound than globular clusters.
The urinary bladder is protected from leaking due to cell-to-cell junctions called?
The urinary bladder is protected from leaking due to tight junctions between epithelial cells. These tight junctions create a barrier that prevents the passage of substances between cells, helping to maintain the integrity of the bladder wall and prevent leakage of urine.
