hey! i want to die - sheep brain lab practical
Cards in this deck (57)
- 1What is the name of the white film that you have to remove from the brain before beginning your dissection?The Dura Mater
- 2What directional view of the brain is this picture in?Ventral
- 3What directional view of the brain is this picture in?Dorsal
- 4What directional view of the brain is this picture in?Posterior/Caudal (caudate)
- 5What fissure is the probe in?longitudinal fissure
- 6What fissure are the probes in?transverse fissure
- 7What is the blue pin marking?pineal gland/body
- 8What is the red pin marking?thalamus
- 9What is the green pin marking?lateral ventricle
- 10With the dura mater still on, what is the the structure labelled with "A"?pituitary gland
- 11With the dura mater still on, what is the the structure labelled with "B"?optic chiasma
- 12What is the structure labelled with red?The olfactory bulb.
- 13What is the structure labelled in black?spinal cord
- 14What is another name for the infundibulum?pituitary stalk
- 15What is the name of the structure labelled in yellow?infundibulum
- 16What is the name of the structure labelled in white?pons
- 17What is the name of the structure labelled in orange?optic chiasma
- 18What ddirectional view can the inferior and superior colliculi be seen in?posterior (caudle) view
- 19What is marked in red?superior colliculi
- 20What is marked in blue?inferior colliculi
- 21What gland can be seen between/behind the superior and inferior colliculi?pineal gland
- 22What lobe is marked with the number 1?frontal
- 23What lobe is marked with the number 2?parietal
- 24What lobe is marked with the number 3?occipital
- 25What is marked with the number 4?cerebellum
- 26What is marked with the number 5?spinal cord
- 27What is marked with the number 6?medulla oblongata
- 28What is marked with the number 8?pons
- 29What is the falx cerebri?the dura mater within the longitudinal fissure
- 30What is the tentorium cerebelli?dura mater separating cerebellum and cerebrum (transverse fissure)
- 31What is the literal English translation of the Latin "dura mater"?tough mother
- 32Why do you think early anatomists called this structure dura mater?it protects the brain?
- 33Explain 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. - 34Why is the frontal lobe in humans larger than in sheep?- Thinking
- Reasoning (judgement)
- Memory
- Speaking - 35Why are there less ridges and contours on a sheep's brain?less need for surface area and connections between neurons
- 36Why 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
- 37Why is the olfactory bulb larger?animals usually rely more upon their senses and abilities of smell than humans do
- 38Why is the pineal gland larger in a sheep?controlling reproduction and circadian rhythms, less basic instinctual behavior controls
- 39Four functions of the cerebrospinal fluid?-Protects brain and spinal cord
-Supplies nutrients
-Removes waste products from cerebral metabolism
-environment for neurons - 40What does the term arbor vitae translate to?tree of life
- 41Identify 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 - 4215pineal gland/body
- 43What is arbor vitae?white matter
- 44What 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
- 45What is the gray matter?the locations of nerve cell bodies and branching dendrites
- 46What is this thingy??corpus callosum
- 47What is a gyrus?a ridge or fold between two clefts on the cerebral surface in the brain
- 48What is a sulcus?a groove or furrow, especially one on the surface of the brain
- 49What does the thalamus do?a relays sensory impulses from receptors in various parts of the body to the cerebral cortex
- 50What lobe is shown here?temporal
- 51What is shown with the number 18?corpus callosum
- 52What 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.
- 53What is the mid-saggital?the middle line that you cut to split the brain in half (I believe)
- 54What is rostral?anterior
- 55proximalsituated nearer to the center of the body or the point of attachment
- 56distalsituated farther from the center of the body or the point of attachment.
- 57Difference between medial and lateral?lateral is to or on the side of something else, while something medial is towards the middle of something
