What else can I help you with?
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 does extrapyramidal mean?
relating to or denoting nerves concerned with motor activity that descend from the cortex to the spine and are not part of the pyramidal system.
What does Machado-Joseph disease involve?
The disease involves the slow and progressive degeneration of brain areas involved in motor coordination, such as the cerebellar, extrapyramidal, pyramidal, and motor areas
What do the neurons of the motor pathway control?
The neurons of the motor pathway control muscle movements by sending signals from the brain to the muscles. These signals coordinate and regulate voluntary movements such as walking, reaching, and grasping.
The descending pathway mostly mediates signals related to walking posture and balance.?
The descending pathway, primarily involving the corticospinal and extrapyramidal tracts, plays a crucial role in regulating voluntary movement, posture, and balance. It transmits signals from the brain to the spinal cord, influencing muscle tone and coordination necessary for maintaining a stable walking posture. This pathway integrates sensory feedback to adjust movements in real-time, ensuring balance and effective locomotion. Overall, its function is vital for coordinated motor control and stability during walking.
What is a contralateral pathway?
A contralateral motor pathway is a neutral pathway located at the opposite side of the brain. It is on the eighth nerve of the cochlear nucleus.
What are the functions of motor cortex?
Pre central gyrus has got the motor cortex. Through this area you get the initiation of final motor pathway.
What is a parasympathetic motor pathway?
Most of the parasympathetic motor pathway goes through oculomotor, facial, glassopharyngeal and vagus nerve. They are third, seventh, ninth and tenth cranial nerves. There is sacral out flow also.
What Consists of all outgoing motor pathways?
The corticospinal tract, extrapyramidal system, and rubrospinal tract together form the major outgoing motor pathways from the brain to the body. These pathways control voluntary movement and posture by transmitting motor signals from the brain to the spinal cord and ultimately to the muscles.
What is the first motor neuron in an autonomic pathway called?
The first motor neuron in an autonomic pathway is called a preganglionic neuron. It originates in the central nervous system and synapses with a postganglionic neuron in an autonomic ganglion.
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.
