What else can I help you with?
What substance crosses the gap between a neuron and a muscle fiber?
This substance is called as neurotransmitter. Here it is acetylcholine.
The response of a motor unit to a single action potential of its motor neuron is called?
The response of a motor unit to a single action potential of its motor neuron is called a muscle twitch. This involves the contraction of all the muscle fibers within the motor unit in response to the stimulation from the motor neuron.
Weak stimulation of a motor neuron causes the muscle to what?
contract weakly
What stops muscle stimulation when the motor neuron ceases firing?
Acetylcholinesterase is the enzyme that stops muscle stimulation when the motor neuron ceases firing. This enzyme enables acetyl and choline to release their binding sites.
The area of the skin where stimulation generates action potentials in a particular sensory neuron is called that neuron's?
receptive field
What structure is the effector for the somatic motor stimulation?
The effector for somatic motor stimulation is the skeletal muscle. Somatic motor neurons innervate these muscles, leading to voluntary movements. The motor unit, consisting of a motor neuron and the muscle fibers it innervates, is responsible for muscle contraction in response to somatic motor stimulation.
What site where the motor neuron and muscle cell meet is called the?
The site where a motor neuron and muscle cell meet is called the neuromuscular junction. This is where the motor neuron releases neurotransmitters that signal the muscle cell to contract.
Just what does pass from neuron to the muscle cells?
via chemicals called neurotransmitters, expressed at sites called synapses, which are tiny gaps between a neuron and another neuron or a muscle cell.
The combination of a neuron and the muscle fibers it associates with is called?
The combination of a neuron and the muscle fibers it associates with is called a motor unit. Motor units work together to produce movement by having the neuron stimulate the muscle fibers it innervates to contract.
A brief change in electrical voltage in the neuron in response to stimulation is called what?
an action potential
What motor neuron and all the muscle fibers it innervates called?
the motor unit
When a neuron transfers an impulse to another neuron or to a muscle cell what is that location that receives the impulse called synapse dendrite receptor NextReset?
The location where a neuron transfers an impulse to another neuron or to a muscle cell is called a synapse. At the synapse, the presynaptic neuron releases neurotransmitters that bind to receptors on the postsynaptic neuron or muscle cell, facilitating the transmission of the signal. This process is crucial for communication within the nervous system and between nerves and muscles.
