Dorsal horn sensory or motor system?
The dorsal horn is afferent or sensory; the ventral horn is efferent or motor. To make it easier to remember, think of A.D.am and E.V.e.
Will a viral disease that destroy neuron cell bodies of the anterior gray horn lead to muscle weakness or paralysis?
Yes, a viral disease that destroys the neuron cell bodies in the anterior gray horn of the spinal cord can lead to muscle weakness or paralysis. The anterior gray horn is responsible for sending signals to the muscles, and if these neurons are destroyed, the muscles will not receive the necessary signals to contract properly, resulting in weakness or paralysis.
Where are located peripheral motor neuron cell bodies?
For spinal nerves, the general somatic efferent motor neurons have their cell bodies located in the ventral horn of the spinal cord (sometimes also called the anterior horn).Some of your cranial nerves also have motor neurons located in various nuclei of the brainstem.
Which structure carries sensory information?
the dorsal horn is involved in sensory functions
What is the Function of upper motor neurons?
Upper motor neurons primarily convey information from your motor cortex to brainstem nuclei (corticobulbar tract) or anterior horn cells in the spinal cord (corticospinal tract). Other tracts exist but are minor or redundant. Upper motor neurons decussate.
What type of signal travels through the anterior gray horn?
The anterior gray horn is an element located in the spinal cord of animals. This element receives and responds to sensory impulses.
Where does synapses occur in the spinal cord?
Cell body of sensory neuron - in dorsal root ganglion. Cell body of motor neuron - in anterior gray horn.
What type of Impulse thravels through the anterior gray horn?
motor
If the anterior horn of gray matter of spinal cord segment T1 is damaged What are the effects of such a condition if any?
there is sensory loss in the medial aspect of the arm
Are motor neuron cells bodies located in the gray or white matter of the spinal cord?
the white matter
Motor impulses leave what horn of the spinal cord?
Motor nerve leaves anterior horn.
Dorsal horn sensory or motor system?
The dorsal horn is afferent or sensory; the ventral horn is efferent or motor. To make it easier to remember, think of A.D.am and E.V.e.
What will a viral disease that destroys the cells of the anterior gray horn do?
This can lead to a number of neurlogical problems, including paralysis, post-polio syndrome (in the case of poliovirus attacking the anterior gray horn), and other symptoms.
What type of impulse travels through the posterior gray horn?
sensory
Which cells from the anterior gray horn are the only ones that terminate in skeletal muscle cells?
Axons from the anterior gray horn are the only ones that terminate in skeletal muscle cells. This principle of the final common path to skeletal muscles has important practical implications.
Will a viral disease that destroy neuron cell bodies of the anterior gray horn lead to muscle weakness or paralysis?
Yes, a viral disease that destroys the neuron cell bodies in the anterior gray horn of the spinal cord can lead to muscle weakness or paralysis. The anterior gray horn is responsible for sending signals to the muscles, and if these neurons are destroyed, the muscles will not receive the necessary signals to contract properly, resulting in weakness or paralysis.
What disease destroys the cells of the anterior gray horn?
Several diseases attack the motor neurons that have cell bodies located in the anterior horn of the spinal column namely: amyotropic lateral sclerosis, spinal muscular atrophies, primary lateral sclerosis, and Kennedy's disease (see the linked article for more detail).
