CSF is not found in the
central canal
third ventricle
The four large, fluid-filled spaces within the brain are called ventricles
Interference of CSF circulation, causing the fluid to accumulate in the subarachnoid space is referred to as external hydrocephalus
❌: transmits impulses of crude touch and pressure ❌: transmits impulses of subconscious kinesthesia ❌: transmits impulses of crude touch, pain, and temperature ❌: transmits impulses of discriminating touch and kinesthesia
❌; transmits impulses that control voluntary movement of muscles on the same side of the body ❌: facilitates head and neck movement related to visual reflexes ❌: helps maintain posture during skeletal muscle movements ❌: transmits impulses that control voluntary movement of muscles on the opposite side of the body ❌: transmits impulses that coordinate body movements and maintenance of posture

skeletal muscle
Absence of reflexes is indicative of injury to
lower motor neurons
upper motor neurons
lower sensory neurons
upper sensory neurons
Poliomyelitis results in flaccid paralysis via destruction of anterior horn neurons.
Extrapyramidal tracts are very simple pyramid tracts.
The portion of the brain stem that joins the spinal cord to the brain is the
diencaphalon
