31
Q

Which main cortex is found in the occipital lobe

A

visual cortex

32
Q

which are is responsible for controlling muscular movement for speaking

A

broca area

33
Q

Which part of the brain receives sensory information such as temperature, pain, touch, pressure from the body?

A

Primary Somatosensory Cortex

34
Q

Which group of axons connect the two hemispheres together within the corpus callosum to communicate with one another?

A

Commissural Tracts

35
Q

What is/are true about cerebrospinal fluid function(s)?

A
  • cushions the brain
  • removes water from cns
  • keep brain buoyant in the skull
36
Q

Which of the meninges is composed of trabeculae that create a subspace for CSF to flow throughout the layer around the brain to remove waste and keep the brain buoyant?

A

arachnoid mater

37
Q

The flow of CSF is composed as followed:

A
  1. lateral ventricles
  2. 3rd ventricle
  3. cerebral aqueduct
  4. ventricle
38
Q

Which layer of the eye converts the visible light into nerve impulses?

A

retina layer

39
Q

Within the lacrimal apparatus, which part empties lacrimal fluid into the nasal cavity?

A

nasolacrimal duct

40
Q

The posterior segment holds which type of liquid that maintains the shape of the eyeball?

A

vitreous humor

41
Q

What is/are true about the image formed by the retina?

A

none of the above

real and inverted

42
Q

The fovea centralis is an area within the retina that only holds what type of sensory receptors?

A

cones

43
Q

Which region of the inner ear sends interprets dynamic equilibrium?

A

semicircular ducts

44
Q

Which region of the inner ear interprets static equilibrium and acceleration?

A

vestibule

45
Q

If I were to do a backflip, which part is stimulated to interpret this motion?

A

anterior semicircular duct

46
Q

Which part of the middle ear is prone to ear infections in children?

A

Eustachian tube

47
Q

What is the potential risk of having the cerebellum damaged? Please explain the potential symptoms as discussed in the lecture and lab.

A

If it was damaged you can risk the function of skeletal movements. Your movements would no longer be precise and smooth. Your posture and equilabrium would be off balance.

48
Q

Explain color blindness.

A

color blidness happens when you lack of one cone type.

cones are the reason that we can see detailed color vision and lack of them disrupts color therefore being color blind.

49
Q

Place the ear ossicles in sequence from the tympanic membrane to the oval window. Spelling counts.

A

Sound waves strike the tympanic membrane and cause vibration. The vibration travels from the ossicles to the oval window.

3 bones conduct vibration in the ear.

Malleus, Incus and stapes.

50
Q

What is the role of an erythrocyte and what special iron protein does it have that makes it essential for the human body?

A

Their main role is to carry oxygen. whats special in ethrocytes is it contains hemoglobin(send oxygen to the rest of the body ), iron-conatining protien.

51
Q

Explain the steps of a negative feedback loop and which hormone is involved in eating 2 birria tacos and washing it down with Jarritos de Tamarindo.
