What else can I help you with?
Type of junction where a motor neuron and a skeleton muscle cell have contact?
Neuromuscular junction. It is the point of contact between the motor neuron and the skeletal muscle cell, where the motor neuron releases neurotransmitters that trigger muscle contraction.
The motor neuron and the muscle fiber it controls constitute a what?
The motor neuron and the muscle fiber it controls constitute a motor unit. This functional unit is essential to the process of muscle contraction and movement in the body. When the motor neuron sends signals to the muscle fiber, it results in the activation and coordination of muscle fibers to produce movement.
What is the name of the point at which motor neuron synapses motor end plate?
The point at which a motor neuron synapses with a muscle fiber's motor end plate is called the neuromuscular junction. This is where the nerve impulse is transmitted from the motor neuron to the muscle fiber, leading to muscle contraction.
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.
Where are the Neurotransmitters that cause skeletal muscle contraction normally stored?
motor neuron axon terminals
What neurotransmitter neuron to muscle cell?
The neurotransmitter acetylcholine is released from neuron axon terminals and binds to nicotinic receptors on muscle cells, triggering muscle contraction.
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 a brief contraction of all muscle fibers in a motor unit in a response to a single action potientia lmoving down the somatic motor neuron is known as what?
A brief contraction of all muscle fibers in a motor unit in response to a single action potential traveling down the somatic motor neuron is known as a muscle twitch. This twitch consists of three phases: the latent period, contraction phase, and relaxation phase. It represents the basic unit of muscle contraction and is essential for understanding muscle function and physiology.
What kind of stimulus travels from the motor neuron to skeletal muscle?
The stimulus that travels from the motor neuron to skeletal muscle is an electrical signal called an action potential. This action potential causes the release of neurotransmitters, specifically acetylcholine, which then stimulates muscle contraction.
Where does a motor neuron send its message?
A motor neuron sends its message, in the form of an electrical signal called an action potential, to a specific muscle to stimulate contraction. This signal travels down the neuron's axon to its terminal branches, where neurotransmitters are released to activate the muscle fibers.
What is a motor neuron attached to?
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
Skeletal muscle fiber is controlled by a motor neuron at a single?
Each muscle cell is only innervated by a single motor neuron, but each motor neuron innervates any number of muscle cells. When an action potential travels down the axon of an alpha motor neuron, it will depolarize several muscle cells at the same time, a phenomenon known as summation.
