There is no junction. Motor neurons are riddled throughout the muscle spindles. Every muscle spindle has a nerve supply or it would not function. think about the way capilaries infiltrate mucles, it's pretty finite. when you are talking about the neurons you are talking about a finite thing, there are billions of them in your body.
What else can I help you with?
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.
A motor neuron together with the muscle fiber it innervates?
it is the motor unit
How is a skeletal muscle fiber stimulated by a motor neuron?
motor unitUnit
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.
What are the 3 structural components of a neuromuscular response?
The three structural components of a neuromuscular response are the motor neuron, the neuromuscular junction, and the muscle fiber. The motor neuron transmits signals from the brain or spinal cord to the muscle, the neuromuscular junction is where the motor neuron and muscle fiber meet and communicate, and the muscle fiber is the contractile tissue that generates force in response to nerve signals.
The synapse of a motor neuron with a muscle fiber is known as the what?
neuromuscular junction
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 the function of motor end plate?
A motor endplate is a large special synaptic contact between motor axons and each skeletal muscle fiber. Each muscle fiber forms one endplate. Its function is to transmit impulses from nerves to muscles.
Each skeletal muscle fiber is controlled by a motor neuron at a single?
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.
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.
What two structures approach each other at a neuromuscular junction?
At a neuromuscular junction, the motor neuron terminal and the muscle fiber membrane (sarcolemma) approach each other. The motor neuron releases the neurotransmitter acetylcholine, which binds to receptors on the muscle fiber membrane, initiating muscle contraction.
