Question | Answer |
The central nervous system (CNS) consists of: | the brain & spinal cord immersed in cerebrospinal fluid (CSF). |
The brain consists of: | the cerebrum, cerebellum, & brain stem. |
The cerebrum is divided into: | 2 hemispheres: left & right. |
Each hemisphere of the cerebrum contains: | 4 lobes: frontal, parietal, occipital, & temporal. |
The outer layer of the brain is: | the cerebral cortex (grey matter). |
The tissue covered by the cerebral cortex (grey matter) containing mostly axons is: | the diencephalon (white matter). |
Corpus callosum is: | the mass of white matter that connects the left & right hemispheres of the cerebrum. |
Basal ganglia is: | a group of specialized clusters of grey matter that assist in coordination. |
Functions of the cortex (cerebral cortex): | Consciousness, emotions, memory, & language. Includes all activity that occurs in cerebrum after sensory signals are recieved. |
Drugs that effect the cerebral cortex include: | caffeine, nicotine, cocaine, & amphetamines. |
The brainstem is the control center for: | vital survival functions. |
The Brainstem is divided into what three parts? | the midbrain, the pons, & the medulla oblongata. |
The cerebellum coordinates: | balance, posture, & movement. |
The vestibular apparatus is important for: | spatial orientation (our senses of equilibrium). |
How many ventricles are there? | four. |
The ventricles provide: | cushioning/protection for the brain & nerves. |
The ventricles circulate: | cerebrospinal fluid (CSF) through the brain & spinal cord. |
The meninges are what? | the three membranes surrounding the brain & spinal cord. |
The dura mater is: | the outer most layer of meninges. |
The arachnoid mater is: | the cobweb-like, middle layer of meninges containing many blood vessels. |
The pia mater is: | the thin, innermost layer of the meninges adhering directly to the brain & spinal cord. |
The epidural space is: | between the skull & dura mater. |
The subdural space is: | between dura mater & arachnoid mater. |
The subarachnoid space is: | between arachnoid mater & pia mater. |
The spinal cord begins: | at the base of the medulla oblongata. |
The spinal cord ends at: | approximately L1/L2. |
There are how many pairs of spinal nerves (that connect the brain & spinal cord to the rest of the body)? | thirty-one |
How many cervical pairs (of spinal nerves)? | eight. |
How many thoracic pairs(of spinal nerves)? | twelve. |
How many lumbar pairs(of spinal nerves)? | five. |
How many sacral pairs(of spinal nerves)? | five. |
How many coccygeal pairs(of spinal nerves)? | one. |
The spinal cord: | is the center for spinal reflexes & conducts nerve impulses. |
