| What is the structure labelled with red? | The olfactory bulb. |
| What is the structure labelled in black? | spinal cord |
| What is another name for the infundibulum? | pituitary stalk |
| What is the name of the structure labelled in yellow? | infundibulum |
| What is the name of the structure labelled in white? | pons |
| What is the name of the structure labelled in orange? | optic chiasma |
| What ddirectional view can the inferior and superior colliculi be seen in? | posterior (caudle) view |
| What is marked in red? | superior colliculi |
| What is marked in blue? | inferior colliculi |
| What gland can be seen between/behind the superior and inferior colliculi? | pineal gland |
| What lobe is marked with the number 1? | frontal |
| What lobe is marked with the number 2? | parietal |
| What lobe is marked with the number 3? | occipital |
| What is marked with the number 4? | cerebellum |
| What is marked with the number 5? | spinal cord |
| What is marked with the number 6? | medulla oblongata |
| What is marked with the number 8? | pons |
| What is the falx cerebri? | the dura mater within the longitudinal fissure |
| What is the tentorium cerebelli? | dura mater separating cerebellum and cerebrum (transverse fissure) |
| What is the literal English translation of the Latin "dura mater"? | tough mother |
| Why do you think early anatomists called this structure dura mater? | it protects the brain? |
| Explain how the sheep brain is different from a human brain. | In humans: larger frontal lobe, longer, heavier, rounded, more contours and ridges. In sheep: less ridges and contours, elongated, brain directed outwards, smaller cerebellum, larger olfactory bulb, larger pineal gland. |
| Why is the frontal lobe in humans larger than in sheep? | - Thinking - Reasoning (judgement) - Memory - Speaking |
| Why are there less ridges and contours on a sheep's brain? | less need for surface area and connections between neurons |
| Why is the cerebellum in a sheep smaller than in a human? | humans and their complex learned behaviors for movement are more nuanced than in sheep |
| Why is the olfactory bulb larger? | animals usually rely more upon their senses and abilities of smell than humans do |
| Why is the pineal gland larger in a sheep? | controlling reproduction and circadian rhythms, less basic instinctual behavior controls |
| Four functions of the cerebrospinal fluid? | -Protects brain and spinal cord -Supplies nutrients -Removes waste products from cerebral metabolism -environment for neurons |
| What does the term arbor vitae translate to? | tree of life |
| Identify the three meninges layers that cover the brain in order from the outermost to the innermost layer. | 1. dura mater 2. arachnoid mater 3. pia mater |
| 15 | pineal gland/body |
| What is arbor vitae? | white matter |
| What is the purpose of white matter? | composed of bundles of myelinated axons that connect various gray matter areas to each other, and carry nerve impulses |
| What is the gray matter? | the locations of nerve cell bodies and branching dendrites |
| What is this thingy?? | corpus callosum |
| What is a gyrus? |
a ridge or fold between two clefts on the cerebral surface in the brain
Image:
Gyrus Sulcus (image/png)
|
| What is a sulcus? |
a groove or furrow, especially one on the surface of the brain

|
| What does the thalamus do? | a relays sensory impulses from receptors in various parts of the body to the cerebral cortex |
| What lobe is shown here? | temporal |
| What is shown with the number 18? | corpus callosum |
| What is the difference between a sheep skull and human skull? Why? | A sheep skull is more elongated with larger nasals because the brain is shaped differently (an affect of where it is positioned on the body) and the sheep's need to smell things. |
| What is the mid-saggital? | the middle line that you cut to split the brain in half (I believe) |
| What is rostral? | anterior |
| proximal | situated nearer to the center of the body or the point of attachment |
| distal | situated farther from the center of the body or the point of attachment. |
| Difference between medial and lateral? | lateral is to or on the side of something else, while something medial is towards the middle of something |
