midterm 3 Flashcards
Area where is cerebral spinal fluid is produced
Choroid plexus
Known as the relay station for sensory impulses
thalamus
Regulates the body temp, controls water balance and regulates metabolism
hypothalamus
the are that regulates our breathing
pons
area the is involved in our ability to speak
broca’s area
fine tunes, coordinates & stores learned patterns of skeletal Muscle movement & provides involuntary coordination of body movements
cerebellum
contains important control centers: cardiac, vasomotor, respiratory
medulla obloganta
reflex centers for vision and hearing
corpora quadrigma
Regulate the endocrine system and attaches to the hypothalamus
pituitary gland
affects daily rhythms by releasing the hormone melatonin in the absence of light
pineal gland
innervates the medial, superior, inferior rectus muscles and inferior oblique muscles of the eye
oculomotor
receives sensory info from the nose, conducting the sense of smell
olfactory
innervates the lateral rectus eye muscles
abducens
receives sensory information from the abdomen, thorax, neck, and root of tongue: conducts motor info to the pharynx& larynx and controls autonomic functions of heart, digestive organs, spleen and kidneys
vagus
innervates intrinsic and extrinsic tongue muscle
hypoglossal
receives fast and touch sensation from posterior tongue and innervates with the pharynx muscles & parotid gland
glossopharyngeal
carries visual stimulus from eyes to thalamus
optic
Controls movement of superior oblique muscles
trochlear
Innervates muscles of facial expression, lacrimal gland, salivary glands and 2/3 taste on anterior portion of tongue
facial
Controls the muscles of mastication and sensation from face
trigeminal
Innervates posterior neck and pharynx muscles
accessory
The growth hormone stimulates insulin growth factor and responsible for muscle growth T/F
True
Aldosterone regulates electrolyte composition & concentration in body fluids. T/F
TRUE
Corticosterone or aka Cortisol is known as the alert/stress hormone. It stimulates lipid & protein metabolism and regulates blood glucose level. T/F
TRUE
Anti-Diuretic Hormone reduces water loss from the body to maintain plasma volume T/F
TRUE
Prolactin stimulates the production of milk in females T/F
TRUE
Follicle Stimulating Hormone stimulates the growth of ovarian follicles and sperm production. T/F
TRUE
Melanocyte Stimulating Hormone stimulates the synthesis of melatonin. T/F
FALSE
Norepinephrine and epinephrine are normally stimulated by the parasympathetic division of our ANS T/F
FALSE
Hypothyroidism is the lack of calcitonin resulting in low energy levels and metabolic rates. T/F
FALSE
Which main cortex is found in the occipital lobe
visual cortex
which are is responsible for controlling muscular movement for speaking
broca area
Which part of the brain receives sensory information such as temperature, pain, touch, pressure from the body?
Primary Somatosensory Cortex
Which group of axons connect the two hemispheres together within the corpus callosum to communicate with one another?
Commissural Tracts
What is/are true about cerebrospinal fluid function(s)?
- cushions the brain
- removes water from cns
- keep brain buoyant in the skull
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?
arachnoid mater
The flow of CSF is composed as followed:
- lateral ventricles
- 3rd ventricle
- cerebral aqueduct
- ventricle
Which layer of the eye converts the visible light into nerve impulses?
retina layer
Within the lacrimal apparatus, which part empties lacrimal fluid into the nasal cavity?
nasolacrimal duct
The posterior segment holds which type of liquid that maintains the shape of the eyeball?
vitreous humor
What is/are true about the image formed by the retina?
none of the above
real and inverted
The fovea centralis is an area within the retina that only holds what type of sensory receptors?
cones
Which region of the inner ear sends interprets dynamic equilibrium?
semicircular ducts
Which region of the inner ear interprets static equilibrium and acceleration?
vestibule
If I were to do a backflip, which part is stimulated to interpret this motion?
anterior semicircular duct
Which part of the middle ear is prone to ear infections in children?
Eustachian tube
What is the potential risk of having the cerebellum damaged? Please explain the potential symptoms as discussed in the lecture and lab.
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.
Explain color blindness.
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.
Place the ear ossicles in sequence from the tympanic membrane to the oval window. Spelling counts.
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.
What is the role of an erythrocyte and what special iron protein does it have that makes it essential for the human body?
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.
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.
