Why does each vertebra have a hole that goes through it?
Combined vertebral foramina forms the spinal canal. The spinal cord of the central nervous system is located within that canal.
Where is the signal to transferred to the association nerve cells?
The signal comes from the brain, down the spinal cord, and down to the nerve cells that need to send the stimulus signal. The signal also runs vice versa, up the spinal cord and into the brain.
What carries sensory information to the spinal cord?
The major descending motor tract FROM the cerebrum is the corticospinal tract. The major ascending sensory tracts TO the cerebrum are the sensorimotor tract and the dorsal column lemniscal system.
What runs through the center of the vertebral column?
the spinal cord
What is the protrusion of the meninges and spinal cord through a defect in the spinal column?
myelomeningocele
Where does motor impulse travel through spinal cord?
ascending tracts
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.
How does information travel from the brain to the lower extremities?
Information travels from the brain to the lower extremities through use of the peripheral nervous system. A signal is sent from the brain through the spinal cord and into muscles of the trunk.
What is the difference between ascending tracts and descending tracts of the spinal cord?
ascending carry sensory information toward the brain.descending convey motor command to the spinal cord.
Why do messages not get mixed up passing through the spinal cord?
There are ascending and descending tracts in the spinal cord. These tracts are nerve fibers bundled together. Messages going to the brain pass through the ascending tracts while messages coming from the brain pass through the descending tracts. These separate paths prevent messages from getting mixed up.
Ascending pathways in the spinal cord convey what?
Sensory information
Where does the nerve impulse travel from the reflex arc?
The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
Which of the following is not an ascending spinal cord nerve fiber tract?
reticulospinal
What are the neurons that conduct the nerve impulses from the spinal cord and the brainstem to the thalamus called?
afferent nerves of the ascending spinal pathways.
What impulses do ascending tracts within the spinal cord carry to the brain?
reflex
In the spinal cord white matter is separated into ascending and descending tracts organized as?
columns
CAN reflex action controlled by spinal cord?
Simple reflexes are controlled by the spinal cord. The message travels from the sense receptors near the skin through the afferent nerve fibers to the spinal cord. In the spinal cord, the messages are relayed through association neurons to the efferent nerve fibers, which carry them to the muscle cells that cause the reflex movement.
