What else can I help you with?
Sensory neurons and motor neurons are connected by?
Sensory neurons and motor neurons are connected by interneurons in the central nervous system. Interneurons help relay signals from sensory neurons to motor neurons, allowing for the coordination of sensory input and motor output in response to various stimuli.
What do all motor neurons manufacture?
Motor neurons manufacture neurotransmitters, specifically acetylcholine, which is responsible for transmitting signals from the neurons to muscles, enabling movement.
Do neurons have the ability to replicate?
No, neurons do not have the ability to replicate. Once they are damaged or lost, they cannot be replaced.
Do neurons get replaced in the human brain?
No, neurons in the human brain do not typically get replaced. Once neurons are damaged or lost, they are not usually regenerated or replaced by new neurons.
What neurons are involved in a reflex?
3 neurons are included in the reflex arc. They are: Afferent neurons (take the message to the spinal cord) (sensory) Association neurons (directs message to the efferent neuron and the brain) (report reflex to the brain) Efferent neurons (takes message to effector) (motor) Not all reflexes have interneurons.
How do damaged motor neurons affect muscles?
Often, a disorder of the motor neurons results in progressive muscle atrophy (shrinking and wasting) of some, if not all, the muscles of the body. Muscle twitching (fasciculation) is common among these disorders
What neurons carry motor impulses?
Motor neurons
Where does many upper motor neurons synapse with lower motor neurons?
Many upper motor neurons synapse with lower motor neurons in the ventral horn of the spinal cord. This is where the cell bodies of lower motor neurons are located, allowing for the direct control of muscle function.
Sensory neurons and motor neurons are connected by?
Sensory neurons and motor neurons are connected by interneurons in the central nervous system. Interneurons help relay signals from sensory neurons to motor neurons, allowing for the coordination of sensory input and motor output in response to various stimuli.
What type of neurons are multipolar?
Motor neurons and intern neurons
Are neurons that relay impulses from sensory neurons to motor neurons?
Sensory Neurons
What is A neuron that can cause muscles to contract?
Efferent motor neurons stimulate muscle contractions.
What would happen to a person if the motor neuron are damaged?
If motor neurons are damaged, a person may experience muscle weakness, paralysis, or atrophy, as these neurons are responsible for transmitting signals from the brain to the muscles. This can lead to difficulty in movement, coordination, and performing daily activities. Additionally, damage to motor neurons can result in conditions such as amyotrophic lateral sclerosis (ALS) or spinal muscular atrophy, which progressively worsen over time. Overall, such damage significantly impacts a person's mobility and quality of life.
Can undamaged neurons make new connection with damaged neurons?
yes
What are neurons that relay impulses from sensory to motor neurons?
Sensory Neurons
What are neurons that carry information between sensory neurons and motor neurons?
Interneurons or association neurons.
Neurons that move impulses from the brain?
Motor Neurons
