What else can I help you with?
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 lies between the sensory neuron and the motor neuron?
Between the sensory neuron and the motor neuron lies the interneuron. Interneurons communicate and process information within the central nervous system, helping to integrate and coordinate sensory inputs with appropriate motor outputs.
What does axon terminal of motor neuron release?
The axon terminal of a motor neuron releases the neurotransmitter acetylcholine. Acetylcholine is responsible for transmitting signals from the motor neuron to muscle fibers, leading to muscle contractions.
What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
What connects sensory to motor neuron?
Interneurons(also called relay neuron, association neuron, connector neuron or local circuit neuron) are multipolar neurons that connects sensory neurons to motor neurons.
Is motor a neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
The point of contract between the nerve ending and the muscle fiber is called a motor neuron?
Neuromuscular junction (NMJ)
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.
What is neuromusclular junction?
Connection between the motor neuron and the muscle fiber. Neuromuscular junction is made up of: 1. Axon ending of the motor neuron (contains the vessicles with acetylcholine ; neurotransmitter) 2. Motor end plate (portion of the sarcolemma that contacts the axon ending) 3. Synaptic cleft (space between the motor neuron and the motor end plate) Impulse--->axon ending--->release of ACH (acetycholine)--->ACH in the synaptic cleft--->ACH binds to the ACH receptors--->release of Calcium from sarcoplasmic reticulum--->Calcium activates Troponin and Tropomyosin--->binding sites are exposed.
What are similarities between sensory and motor neuron?
Motor neuron has got a motor.. but you have to peddle sensory neurons.
What is the 3 types of neuron?
one type of neuron is the motor neuron
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 is a motor neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
Is motor neuron disease the same as ALS?
no yes, it is Lower Motor Neuron Disease
Where is the motor neuron located?
The motor neuron cells are all in the brain and the spinal cord.
What is the difference between a motor unit and a motor neuron in the context of muscle movement?
A motor unit consists of a motor neuron and the muscle fibers it controls. The motor neuron sends signals to the muscle fibers to contract, while the motor unit refers to the combination of the neuron and the muscle fibers it innervates.
