| A | B |
|---|
| Ventricle | spaces in the brain filled with cerebrospinal fluid |
| Temporal lobe | memory, auditory, and olfactory |
| Precentral gyrus | primary motor |
| Pituitary gland | "master gland" because of its control over all other glands |
| Parieto-occipital fissure | divides the occipital and parietal lobes |
| Optic chiasma | regaion where the right and left optic nerves cross over |
| Medulla oblongata | controls vital functions, such as respiration and BP |
| Lateral fissure | separates the temporal lobe from the frontal and parietal lobes |
| Frontal lobe | higher intellect, association, contains primary motor gyrus and motor speech area |
| Corpus callosum | connects the cerebral hemispheres |
| Cerebellum | regulates posture and coordinates skeletal muscles |
| Broca's area | motor speech |
| Thalamus | relay station for afferent fibers, traveling to sensory cortex for interpretation |
| Postcentral gyrus | primary somatic sensory |
| Pons | regulates respiratory rhythm |
| Pineal body | secretes melatonin, "body's clock" |
| Parietal lobe | speech and reading, contains primary somatic sensory gyrus |
| Occipital lobe | visual |
| Longitudinal fissure | divides the cerebral hemispheres |
| Hypothalamus | regulates water balance and temperature, "drive center" |
| Choroid plexus | forms cerebrospinal fluid |
| Central fissure | divides the frontal and parietal lobes |
