The synapse of a motor neuron with a muscle fiber is known as the what?
neuromuscular junction
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.
What substance crosses the gap between a neuron and a muscle fiber?
This substance is called as neurotransmitter. Here it is acetylcholine.
Does the motor neuron send a signal to or from the muscle fiber?
Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.
What is sacrolemma?
The sarcolemma is the cell membrane of a muscle fiber. It surrounds and protects the muscle fiber and controls the movement of substances into and out of the cell. The sarcolemma plays a crucial role in muscle contraction and the transmission of nerve impulses to the muscle fiber.
What is the place where a neuron communicate with a muscle fiber or gland or another neuron?
synapse
How are the Neuron and skeletal muscle fiber connected?
they are connected with the rope in the body
A motor neuron together with the muscle fiber it innervates?
it is the motor unit
What is the substance that halts the stimulation of a muscle fiber by a neuron called?
acetycholinesterase
How is a skeletal muscle fiber stimulated by a motor neuron?
motor unitUnit
The synapse of a motor neuron with a muscle fiber is known as the what?
neuromuscular junction
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.
Each skeletal muscle fiber is controlled by a motor neuron at a single?
neuromuscular junction
What is the enzyme found in the synaptic space between a neuron and a muscle fiber that breaks down the excitatory neurotransmitter chemical that originally caused the muscle fiber to contract called?
acetylcholinesterase
What substance crosses the gap between a neuron and a muscle fiber?
This substance is called as neurotransmitter. Here it is acetylcholine.
The point of contract between the nerve ending and the muscle fiber is called a motor neuron?
Neuromuscular junction (NMJ)
Does the motor neuron send a signal to or from the muscle fiber?
Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.
