ANSWERS) AND RATIONALES /
ALREADY GRADED A+
Anatomy - ANSWER ✓ learning the body structures and the relationship among
them
- through dissections or medical imaging
Hyperextension - ANSWER ✓ extension beyond anatomical position of joint
abduction and adduction - ANSWER ✓ movement away from and toward the
body
Circumduction - ANSWER ✓ the circular movement at the far end of a limb
rotation - ANSWER ✓ - bone revolves around it own longitudinal axis but causes
a movement of left and right
elevation and depression - ANSWER ✓ Up and Down movements such as
opening and closing ones mouth, shrugging shoulders etc.
protraction and retraction - ANSWER ✓ Anterior / posterior movement along
transverse plane
Ex. Mandible (stick chin out / pull chin back)
inversion and eversion - ANSWER ✓ movements of the sole of the foot medially
or laterally
, Dorisflexion and plantar flexion - ANSWER ✓ up and down movements of the
foot (dorisflexion-up, plantar-down)
supination and pronation - ANSWER ✓ rotational movement, results in the palm
facing upward/downward
plane joints - ANSWER ✓ are flat or slightly curved
- permit back and fourth, side to side movements between flat surfaces of bones
hinge joints - ANSWER ✓ Joints that can bend and straighten but cannot rotate;
they restrict motion to one plane.
pivot joints - ANSWER ✓ rounded surface of one bone that articulated with a ring
formed partly by another bone and ligament
- allows rotation on its longitudinal axis
- head turning side to side
condylar joint - ANSWER ✓ a shallow ball-and-socket joint with limited mobility
- flexion/extension and abduction and adduction
Ball and Socket Joints - ANSWER ✓ consists of a ball like surface of one bone
fitting into a cuplike depression of another bone
- multiaxial and permits movement of three axis's
temporomandibular joint - ANSWER ✓ - A combined hinge and plane joint
formed by the condylar process of the mandible and the mandibular fossa and
articular tubercle of the temporal joints
- The mandible is the only moveable bone in the skull
shoulder joint - ANSWER ✓ a ball and socket joint formed by the head of the
humerus and the glenoid cavity of the scapula
elbow joint - ANSWER ✓ a hinge joint formed by the trochlea and capitulum of
the humerus, the trochlear notch of the ulna, and the head of the radius
- flexion and extension
hip joint - ANSWER ✓ a ball and socket joint formed by the head of the femur
and the acetabulum of the hip bone
,- multiaxial
knee joint - ANSWER ✓ complex and large joint
- modified hinge joint consists of three joints within a single synovial cavity
origin of muscle - ANSWER ✓ the attachment to the stationary bone
Insertion of muscle - ANSWER ✓ the attachment to the moveable joint
reverse muscle action - ANSWER ✓ when the origin moves towards the insertion
first class lever - ANSWER ✓ the fulcrum is between the effort and load
second class lever - ANSWER ✓ the load is between the fulcrum and the effort
third class lever - ANSWER ✓ the effort is between the fulcrum and the load
Effects of Fascicle Arrangement - ANSWER ✓ muscle fibers are arranged in
parallel bundles within fascicles but the arrangement of fasciculi in relation to the
tendon can vary
fascicular arrangement is correlated with:
- the amount of power a muscle can produce
- the range of motion a muscle can produce
parallel muscle fibers - ANSWER ✓ Muscle fascicles are parallel to the
longitudinal axis. (ex: biceps brachii and rectus abdominis)
pennate muscle fibers - ANSWER ✓ muscle fibers form an oblique angle to the
tendon of the muscle
- increases power but decreases ROM
facial muscles - ANSWER ✓ The muscles associated with the eyelid, lips, nose,
and auricle of the ear
- buccinator, orbicularis occuli, orbicularis orris, zygomaticus major/minor
Facial muscles are innervated by - ANSWER ✓ CN VII (facial nerve)
- CN 7
, buccinator muscle - ANSWER ✓ muscle of the side of the face that moves the
cheek
- allows for you to suck on a straw
- innervated by cranial nerve 7
orbicularis occuli - ANSWER ✓ muscle that surrounds the eye and closes the eye
- innervated by cranial nerve 7
orbicularis oris - ANSWER ✓ muscle that surrounds the mouth and helps open
and protrudes the mouth
- innervated by cranial nerve 7
zygomaticus major - ANSWER ✓ the muscles at the angle of the mouth
- retracts and elevates corner of mouth
- cranial nerve 7
zygomaticus minor - ANSWER ✓ the muscles on the upper lip
- draws up the upper lips exposing the maxillary teeth
- cranial nerve 7
depressor anguli oris - ANSWER ✓ at the angle of the mouth
- draws the mouth down
- cranial nerve 7
levator anguli oris - ANSWER ✓ - elevates the mouth up
-cranial nerve 7
muscles of mastication - ANSWER ✓ masseter, temporalis, medial pterygoid,
lateral pterygoid
- innervated by trigeminal nerve 5
masseter - ANSWER ✓ raises the mandible, closes and raises the mouth
- trigeminal nerve 5
temporalis - ANSWER ✓ elevates and retracts mandible
- trigeminal nerve 5
