which of the following describes a function of cerebrospinal fluid 1. mechanical protection 2. ph homeostasis 3. circulation
all of the above
cerebrospinal fluid carries small amounts of chemicals like glucose from the --------- to neurons and neuroglia
this protects the brain by preventing the movement of harmful substances and pathogens from the blood int the brain tissue
blood brain barrier
this is a narrow fluid filled cavity foudn along the midline superior to the hypothalamus and between the right and left halves of the thalamus
cerebrospinal fluid is reabsorbed through these fingerlike projections found in the dural venous sinuses
this is a netlike region of white and gray matter that extend throughout the brainstem and functions to help maintain consciousness
this structure in the brain contains centers responsible for the the startle reflex in response to loud sounds
medullary nuclei are 1. masses of gray matter in the medulla oblongata 2 masses of white matter in the medulla oblongata 3decussations of the pyramids
This region of teh brain contains pneumotaxic and apneustic areas that help control respirtaion
The medial lemnisus is a band of white matter that extnds through 1. the medulla oblongata 2. pons 3. midbrain
This region of the brain servbes as the maor relay station for most sensory impulses that reach the primary sensory areas of the cerebral cortex form the spinal cord and brain stem
during brain deveelopment the gyri of the cerebrum are formed because
the gray matter grows faster than the underlying white matter
this portion of the limbic system lies between the hippocampus and the parahippocampus gyrus
Which of teh following functional areas of the cerebrum is responsible for conscious movements of the body
