The Brain
BIO 290 Anatomy James Madison University
| Question | Answer |
|---|---|
| What makes up 83% of the brain mass and is the outermost portion? | Cerebrum |
| What is the very thin layer of cerebrum called? | Cerebral cortex |
| What divides the cerebrum? | Longitudinal fissure |
| What is the cortex made up of? | Gray matter (neuron cell bodies, short unmyelinated axons, dendrites) |
| What is the job of the cortex? | Allows us to be conscious beings, aware of ourselves, communication, memory, move, and understand things. |
| What function does the frontal lobe have? | Concentration and problem solving |
| What function does the parietal lobe have? | Understanding speech |
| What function does the temporal lobe have? | Hearing |
| What function does the occipital lobe have? | Sight |
| What does the corpus callosum do? | Transmits impulses from hemisphere to hemisphere |
| What does the thalamus "z dot" do? | Acts to relay sensory information from =the spinal cord. Structures communicating with the cerebral cortex but send information to the thalamus first |
| What structure projects inferiorly from the hypothalamus? | Pituitary gland |
| What is the function of the hypothalamus? | Involuntary control center for body temperature, sleep-wake ccle, endocrine system, hunger, thirst, sex drive, fear, pleasure, rage (feelings) |
| If an individual contracts a lesion on the hypothalamus, what problems might they have? | Emotional problems and visceral disorders |
| What is the function of the midbrain? | Unconscious and startle reflexes |
| What do the pons do? | Inhalation and exhalation, relay sensory impulses to cerbrum |
| What does the medulla oblongata do? | Connects spinal cord with brain, cardiac, heart rate, breathing, and blood pressure regulation |
| What does the cerebellum do? | Controls and coordinates posture and contraction of skeletal muscles. |
| What structure produces CSF in the brain? | Choroid plexuses |
| What part of the spinal cord is filled with CSF? Where else in the brain? | Central canal, ventricles, and subarachnoid space |
| Whst is the brain floating in? | CSF |
| What is the outermost meninge of the brain? | Dura mater |
| What is the falx cerebri? | Part of the dura mater that extends into the longitudinal fissure. |
| Which meninge is deep to dura mater? | Arachnoid mater |
| What meninge is deep to the arachnoid mater and clings to the brains convolutions? | Pia mater |
| What artery(s) supply the cerebrum and orbits | Right and left internal carotid arteries |
| What artery(s)supply the midbrain and hindbrain? | Right and left vertebral arteries |
| What artery(s) supply the pons, midbrain, medulla, cerebellum, and inner ear? | Basilar artery |
| The basilar atery is a conjunction of what two arteries? | R+L vertebral arteries. |
| What arteries make up the Circle of Willis? | R+L internal carotid, and R+L vertebral (basilar a. included) |
| Name the drainage pattern of blood into the dural sinuses. | Inferior saggital -> straight sinus -> transverse sinus -> sigmoid sinus -> internal jugular vein (via jugular foramen) |
| What part of the brain gives us consciousness? | Cortex |
| What drains csf? | Dural sinuses |
| What makes up the dural sinuses? | Two layers pf dura mater |
| Where do the R+L internal carotid arteries come through the skull? | Carotid canal |
| What supplies the midbrain and hindbrain? | Right and left vertebral arteries |
| What supplies the cerebrum? | R+L internal carotid aa |
| Circle of willis? | Anastomosis (joining) of the R+L internal carotid aa and the R+L vertebral aa's in the brain. -Provides multiple pathways for blood flow to brain in case of damage to either artery |
| Where is the falx cerebelli? | Deep to tentorium cerebelli, supports cerebrum to keep it from crushing the cerebellum |
| Where is the tentorium cerebelli? | Between cerebrum and cerebellum |
| Where is the falx cerebri? |
