On The Test Flashcards
Syntharthosis tendon
Considered immovable/ fibrous.
Ex: skull sutures, the articulations between the teeth and the mandible, and the joint found between the first pair of ribs and the sternum.
Ampiarthrosis tendon
Slightly movable/ cartilaginous
Ex: the distal joint between the tibia and the fibula and the pubic symphisis of the pelvic girdle.
Diarthrosis tendon
Freely movable/ synovial
Ex: elbow, shoulder, and ankle
Orbicularis Occuli
O: Frontal and Maxillary bones
I: Inserts into itself
A: Closes eyelids as in blinking and squinting
What is the oris?
Mouth
Aponeurosis
Flat broad tendon
Corrugator Supercilii (To wrinkle)
O: Frontal bone
I: Skin of eyebrows
A: Draws eyebrows together as in frowning
Orbicularis Oris
O: Muscles + skin around mouth
I: Inserts into itself
A: Closes and protrudes the lips, kissing muscle
Levator Scapulae
O: C1-C4 on transverse process
I: Vertebrial border of scapulae from superior angle to root of spine
A: Elevation of shoulder
Scapula
Pectoralis Minor
O: Anterior surface of 3rd, 4th, 5th rib
I: Corcoid process of scapula
A: Draws scapula anteriorly and downward
Pollicis
Thumb
Pollicis Flexor Longus
O: Middle of anterior radius/ interosius membrane
I: Distal flanex of thumb
A: Flexion of thumb at its joint
Accetabulum
Articulates with head of femur. On illium, is illiac crest, superior edge of illium.
Psoas Major
O: Transverse processes and bodies of t12 and all lumbar Vertebrae and discs
I: Lesser trocanter of femur
A: Flexes thigh and trunk on femur as in rising to sitting position from supine. Assists in outward rotation of thigh and strong postoral muscle. Swings leg forward while walking. Is a chief culprit of low back pain. Can be emotional muscle with heavy sexual connotations.
Pectineus
O: Superior reymus of pubis
I: Posterior surface of femur just below Lesser trocanter
A: Adducts, Flexes, and laterally rotates thigh
Hallicis
Great toe
Ratinaculum
Ligament that prevents tendons from sliding out of place

Massateur and Temporal bones
Isometric contraction
Muscles contract but no movement
What is the most superficial muscle of the back?
Trapezius
What does brachialis attach to?
Corcoid process
What does bicep brachii do?
Flexion of forearm
What does interosius membrane do?
Connects tissue of bones
