Question Answer
What is the name of the white film that you have to remove from the brain before beginning your dissection? The Dura Mater
What directional view of the brain is this picture in? Ventral
What directional view of the brain is this picture in? Dorsal
What directional view of the brain is this picture in? Posterior/Caudal (caudate)
What fissure is the probe in? longitudinal fissure
What fissure are the probes in? transverse fissure
What is the blue pin marking? pineal gland/body
What is the red pin marking? thalamus
What is the green pin marking? lateral ventricle
With the dura mater still on, what is the the structure labelled with "A"? pituitary gland
With the dura mater still on, what is the the structure labelled with "B"? optic chiasma
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
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
