Carry sound waves to the auditory ossicles
33
Cochlea function
Transform vibrations of the cochlear liquids into neural signal
34
Vestibule function
Responds to changes in the position of the head with respect to gravity
35
Vestibucocchlear nerve
Responsible for both hearing and equilibrium and brings information from the inner ear to the brain
36
Parts of the rib cage
Manubrium Body Xiphoid
37
Parts of the upper limbs
``` Clavicle Scapula Humerus Radius Ulna Carpals Phalanges ```
38
Parts of the lower limbs
``` Femur Tibia Fibula Patella Tarsals Phalanges ```
39
Parts of the pelvis
Ilium Ischium Pubic
40
Lobes of the cerebrum
Frontal lobe Parietal lobe Occipital lobe Temporal lobe
41
Parietal lobe function
Perception of touch, pressure, pain, taste, temperature
42
Temporal lobe function
Hearing, smell, memory, emotional behavior, visual recognition
43
Occipital lobe function
Visual centers of the brain
44
Frontal lobe function
Memory, planning, emotion, speech, judgement, mood, voluntary control of skeletal muscle, and aggression
45
Meninges function
Protect and nourish the brain
46
Importance of sutures
Allow for a tiny amount of movement. Contributes to the compliance and elasticity of the skull. Sutures allow the bones to move during the birth process. They act like an expansion joint, allowing the bone to enlarge evenly as the brain grows and the skull expands, resulting in a symmetrically shaped head
47
Types of taste buds
``` Sweet Salty Sour Bitter (Umami) ```
48
Location of sweet taste buds
Tip of tongue
49
Location of salty taste buds
Front and front sides of tongue
50
Location of sour taste buds
Sides of tongue
51
Location of bitter taste buds
Back of tongue
52
Location of umami taste buds
Entire tongue
53
Cerebrum function
Associated with higher brain function such as thought and action. Divided into four lobes
54
Cerebellum function
Motor coordination, monitoring sensory input, muscle movements, and muscle tone
55
Diencephalon function
Contains the epithalamus, thalamus and hypothalamus.
56
Thalamus function
Final relay point for ascending sensory information going to the primary sensory cortex; involved in emotion, motivation, touch, pain, temperature, position, visual and auditory signals
57
Hypothalamus function
Thirst, eating, body temperature, circadian rhythms
58
Midbrain function
Associated with vision, hearing, motor control, sleep/awake, arousal, and temperature regulation
59
Pons function
Connects cerebellum to other parts of the brain and spinal cord; contains sensory and motor nuclei that involve sleep, respiration, swallowing, hearing, equilibrium, taste, eye movements, bladder control, and movements of the head
60
Medulla function
Center for autonomic regulation of heartbeat, breathing, constriction and relaxation of blood vessels, sneezing, coughing, gagging, vomiting, hiccups, and swallowing
61
Gray vs white matter
Gray matter contains the cell bodies, dendrites, and axon terminals of neurons. It includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control. White matter is composed of bundles of myelinated axons which connect various gray matter areas and carry nerve impulses between neurons
62
Pathway of vision
light through the eye to the cornea - aqueous humor - through pupil - lens - vitreous humor - retina - optic nerve - brain - the occipital lobe
63
Ear's role in balance
The inner ear is responsible for balance Vestibular system: Balance organs in the inner ear tell the brain about the movements and position of your head. There is a set of three tubes (semi-circular canals) in each ear, and these sense when you move your head around and help keep your vision clear.
64
Ear's role in hearing
All three parts of the ear are involved in hearing. The outer ear is composed of the pinna, or ear lobe, and the external auditory canal. Both structures funnel sound waves towards the ear drum or tympanic membrane allowing it to vibrate.
65
Types of joints
1. Synarthrosis (no movement) 2. Amphiarthrosis (little movement) 3. Diarthrosis (free movement)
66
Example of synarthrosis joints
sutures of the skull
67
Example of amphiarthrosis joints
The articulation between the vertebrae at the intervertevral discs
68
Example of amphiarthrosis joints
The articulation between the vertebrae at the intervertevral discs
69
Example of diarthrosis joints (synovial)
knee, hip, ankle, elbow, shoulder
70
Types of diarthrosis joints (synovial)
- Hinge joints (elbow, knee) - Ball and socket (humerus/pectoral, femur/pelvis) - Gliding (wrists, ankles) - Pivot (atlas, axis)
71
Flexion of the elbow example
Doing bicep curl weight lifting
72
Extension of the knee example
Walking
73
Opposition of the thumb example
Picking something up with your hand
74
Eversion of the ankle
Rotating your ankle
75
Adduction of the arm
Trying to hug someone
76
Elevation of the shoulder
Shrugging your shoulders
77
Rotation of the neck
Turning your head to look at something
78
Circumduction of the arm
Swimming
79
Compare and contrast the CNS and PNS
- CNS contains the brain and spinal cord. With the help of the PNS, it has a fundamental role in the control of behavior. - PNS consists of the nerves and ganglia outside of the brain and spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs
80

1. Putrid 2. Pungent 3. Minty 4. Floral 5. Musky 6. Ethereal 7. Camphoraceous 8. Fishy
81
Two major functions of the ear
