Why are lower motor neurons referred as the finals pathway?
Lower motor neurons are referred to as the final pathway because they are the last stage in the neural circuitry that conveys motor commands from the central nervous system to the muscles. They directly innervate the muscles and are responsible for initiating muscle contraction and generating movement.
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.
The motor pathway of the autonomic nervous system usually involves how many neurons?
The motor pathway of the autonomic nervous system typically involves two neurons: a preganglionic neuron that originates in the central nervous system and a postganglionic neuron that extends to the target tissue or organ.
The descending pathway from the red nucleus to the lower motor neurons is the Tract?
The descending pathway from the red nucleus to the lower motor neurons is known as the rubrospinal tract. This tract plays a role in the coordination of movement and the regulation of muscle tone, particularly in the upper limbs. It originates in the red nucleus of the midbrain and descends to influence motor neurons in the spinal cord, primarily facilitating flexor muscle activity.
What motor pathway is primarily concerned with automatic control of body parts for coordination?
Extrapyramidal pathway
What is the neurotransmitter in a somatic motor pathway?
The neurotransmitter in a somatic motor pathway is acetylcholine. It is released by motor neurons at the neuromuscular junction to stimulate muscle contraction.
What is the descending pathway from the red nucleus to the lower motor neurons is the tract.?
The descending pathway from the red nucleus to the lower motor neurons is known as the rubrospinal tract. This tract arises from the red nucleus in the midbrain and descends through the brainstem and spinal cord. It primarily facilitates the control of motor function, particularly in the upper limbs, by influencing the activity of lower motor neurons that innervate skeletal muscles. The rubrospinal tract is involved in the modulation of voluntary movements and reflexes.
What carries the nerve impulse from the central nervous system to an effector?
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
What type of nuerons conduct nerve impulses along an efferent pathway?
Motor neurons
What are neurons that control skeletor effectors called?
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.
Where is the first synapse in the motor pathway?
The first synapse in the motor pathway occurs in the anterior horn of the spinal cord. Motor neurons, which originate in the motor cortex of the brain, send their axons down through the corticospinal tract and synapse with lower motor neurons located in the anterior horn. This connection is crucial for transmitting motor commands from the central nervous system to skeletal muscles.
The motor pathway of the autonomic nervous system usually involves how many neurons?
The motor pathway of the autonomic nervous system typically involves two neurons: a preganglionic neuron that originates in the central nervous system and a postganglionic neuron that extends to the target tissue or organ.
What is a neuron serving as part of the conduction pathway between sensory and motor neurons?
Interneurons are neurons found within the central nervous system (primarily the brain or spinal cord) that connect sensory (afferent) neurons to motor (efferent) neurons. Often these neurons are part of a polysynaptic reflex arc.interneurons. They are also called association neurons.
