name of Cells that release ACh into the synaptic cleft of a neuromuscular junction?
name of Cells that secret the hormone "glucagon" ?
The cells that release acetylcholine (ACh) into the synaptic cleft of a neuromuscular junction are called motor neurons. To arrive at this answer, we can break down the question and understand the key terms involved.
Firstly, a neuromuscular junction is the point of connection between a motor neuron and a muscle fiber. It is where the nervous system communicates with the muscles to initiate muscle contraction.
Secondly, acetylcholine is a neurotransmitter that is responsible for transmitting signals between neurons and between neurons and muscles. In the context of a neuromuscular junction, ACh is released by motor neurons to activate the muscle fibers.
Therefore, the cells that release ACh into the synaptic cleft of a neuromuscular junction are motor neurons.
Moving on to the second part of the question, the cells that secrete the hormone "glucagon" are called alpha cells. Glucagon is a hormone produced by the alpha cells of the pancreas. Its primary function is to increase blood sugar levels by stimulating the liver to convert stored glycogen into glucose.
To determine this answer, we need to understand the role of the pancreas and the specific cells involved in the production of glucagon. In the pancreas, there are different types of cells that secrete various hormones, including alpha cells that produce glucagon.
