What is the space between two neurons called?
The space between the ending of one neuron and the communication with the next neuron is called the synapse, or sometimes it is called the synaptic gap or synaptic cleft. But synapse is the common term.
The part of the neuron which collects and combines information is called the?
soma
Neurotransmitter that triggers muscle contraction?
Acetylcholine (ah-Seh-til-KO-leen) is the organic molecule that triggers muscle contractions in humans. Acetylcholine acts on both the central nervous system (CNS) and on the peripheral nervous system (PNS). It is also the principal neurotransmitter in autonomic ganglia.
What happens if one of your leg motor neuron stop functioning?
The leg wouldn't be able to receive or transmit impulses and information from the central nerves system CNS to the muscle and glands
When a nervous impulse travels from a neuron to a muscle cell what happens next?
When a signal reaches the end of a neuron it releases neurotransmitters into the synapse where they bind to receptors to release the second messenger into the next neuron.If you are confused I highly recommend this website: http:/learn.genetics.utah.edu/content/addiction/reward/neurontalk.html
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.
What is a motor unit is made up of?
Motor neurons and the muscle fibers they transmit signals toA motor unit is a collection of muscle fibers that contract as a single functional unit when stimulated by an impulse from a motor neuron. The actual size can vary greatly, from many large muscle fibers in the quadriceps muscle group per motor unit to just a few muscle fibers in the muscles of the fingers per motor unit.
Define motor unit?
A motor unit consists of a motor neuron and all the muscle fibers it innervates. When the motor neuron fires, all the muscle fibers in the motor unit contract simultaneously. This coordinated activation allows for precise control of muscle force and movement.
What is it called when muscles and nerves group together?
When muscles and nerves group together, it is called a motor unit. A motor unit consists of a single motor neuron and all the muscle fibers it innervates. When the motor neuron fires, all the muscle fibers in the motor unit contract together.
When a single neuron sends a strong enough impulse to a muscle that how many muscle fibers does it cause to contract?
When a single neuron sends a strong enough impulse to a muscle, it can cause multiple muscle fibers within that muscle to contract. The specific number of muscle fibers that contract will depend on factors like the size of the motor unit and the intensity of the signal from the neuron.
A motor neuron together with the muscle fiber it innervates?
it is the motor unit
What consists of a somatic motor neuron plus all the skeletal muscle fibers it stimulates?
A motor unit consists of a somatic motor neuron and all the skeletal muscle fibers it innervates. When the motor neuron fires an action potential, all the muscle fibers in its motor unit contract simultaneously. Motor units vary in size depending on the precision of movement required, with smaller units needed for fine control and larger units for more powerful movements.
A motor neuron and the muscle fibers it controls are called?
the motor unit
When a preganglionic neuron innervates several postganglionic neurons it is called what?
divergence
A motor neuron transmits signals to?
Muscle fibers
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.
Once a motor neuron has fired all the muscle fibers in a muscle contract.?
False
