Neurons come in many sizes. For example, a single sensory neuron from your fingertip has an axon that extends the length of your arm, while neurons within the brain may extend only a few millimeters. Neurons have different shapes depending on what they do. Motor neurons that control muscle contractions have a cell body on one end, a long axon in the middle and dendrites on the other end; sensory neurons have dendrites on both ends, connected by a long axon with a cell body in the middle.
What else can I help you with?
What is the function of a gamma motor neuron?
It is a ray of radiation. conducts muscle movement.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What happens when a motor neuron in a reflex arc is damaged?
When a motor neuron in a reflex arc is damaged, the transmission of signals from the spinal cord to the muscles is interrupted. This can result in a loss of motor function or muscle weakness in the affected area, as the muscles can no longer receive the necessary signals to contract. Consequently, reflex actions involving that motor neuron may be diminished or absent, leading to impaired reflex responses. Overall, damage to a motor neuron disrupts the normal functioning of the reflex arc.
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.
What is the function of relay neuron?
Relay neurons, also known as interneurons, transmit signals between sensory neurons and motor neurons in the central nervous system. They play a key role in integrating and interpreting sensory information before sending signals to motor neurons for response or further processing. Relay neurons help coordinate complex behaviors and responses in the body.
What is the function of a relay neron?
transmission of nerve impulses from the sensory neuron to the motor neuron,located in the central nervous system.
What is the function of a gamma motor neuron?
It is a ray of radiation. conducts muscle movement.
What are the function of motor neuron?
The function is to catch/take impulses from the central nervous system and send it to muscles and glands
Dendrites function in the motor neuron?
To carry the nerve impulse from the CNS to the cell body
What is the function motor neurons?
The function of a motor neuron is to be a path of transport. It is a path that transmits impulses to the effector tissues like muscles and glands from the central nervous system.
Is motor a neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
How are motor and sensory neurons categorized?
Motor Neuron and Sensory Neuron
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.
In humans one function of an interneuron is to relay impulses directly from?
In humans, one function of an interneuron is to relay impulses directly from sensory neurons to motor neurons. This allows for a quick response without involving the brain in every reflex action.
What is the function of an efferent neuron?
nerve fibres which carry the commands from the CNS out to (muscles, organs, glands) for a motor output or response.
What are similarities between sensory and motor neuron?
Motor neuron has got a motor.. but you have to peddle sensory neurons.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
