Parotid duct

Carries saliva from the parotid gland to the mouth by coursing anteriorly, superficial to masseter m
At anterior border of the masseter m, it turns medially and penetrates the buccinator m to open into the mouth opposite the upper second molar

Parotid gland

Largest salivary gland
Superficial to lower part of masseter muscles
Pierced by 7 but innervated by 9

Larynx is for

Phonation

Vocal cords are stretched by

CRICOTHYROID mm

Vocalis m

Makes tiny local adjustments to the tension of the vocal ligament during speech

Lateral cricoartynoid mm

ADDucts the vocal cords

Posterior cricoarytenoid mm

Abducts the vocal cords

CN 3 on

SR, IR, MR, IO, LPS m

Trochlear on

Superior cervical sympathetic ganglion innervates

Dilator papillae m Superior tarsal m

Pupillary light reflex

Sensory by 2 Motor by 3

Corneal reflex

V1 provides sensory 7 provides motor limb

Cataract

Loss of transparency

Glaucoma

Increased intra ocular PRESSURE usually bu obstruction of flow of aqueos humor in the anterior compartment of the eye

Acetabulum

Ilium, ischium and pubis Socket holds head of femur Acetabular labrum = fibrocartilaginous lip that helps deepen the socket

Broken hip

Fracture of neck of femur

Trendelenburg gait

Damage to superior gluteal n Gluteus minimus and medius cant prevent the tilt

Piriformis syndrome

Enlarged piriformis m Compress sciatic n

Mm of medial thigh supply

Innervated by obturator n Blood via obturator a and perforating branches of deep femoral artery Primary adductors of the thigh

Is iliopsoas part of anterior thigh

Not really but it is a major flexor of the hip joint and considered a part of it

Broken hip

Fracture of neck of femur

Obturator artery supplies

Some of medial and posterior thigh

Obturator nerve innerv

Medial compartment of the thigh (adductors) NOT hamstring part of adductor magnus (tibial n does)

Femoral nerve innervates

Anterior compartment of the thigh (thigh flexors and leg extensors)

What does the capsule surrounding the knees produce

Synovial fluid , protein rich secretion that is very slippery

Test medial collateral ligament

Valgus stress test

Test LCL

Varus stress test Adduct

Test ACL

Anterior drawer test Knee 90 degrees Tibia pulled anterior

Lachman test

ACL test Knee is 30 degrees Tibia pulled anteriorly

PCL test

Posterior drawer test Knee 90 and pull tibia post

McMurray test

Medial or lateral meniscus

Ankle joint

Hinge-like mortise and tenon joint between the tibia fibula and talus bones

Ankle joint stabilization

Most stable when Dorsiflexed and LEAST stable when plantar flexed due to slight anteroposterior sliding of the talus during these movements

Anterior compartment of the leg

Innervation by deep fibular nerve Supplied by anterior tibial artery

Lateral compartment of leg

Nerve by superficial fibular nerve Supplied by perforating branches of the fibular artery

Posterior compartment of the leg

Innervated by tibial nerve Supplied by posterior tibial artery

What provides most of the support for the arches of the foot

Plantar calcaneonavicular ligament , long plantar ligament, and short plantar ligament

Plantar aponeurosis

Vey dense fibrous band of tissue; assists in maintaining the arch, rebounding with each walking step

Muscles of planetary compartment innervated by

Terminal branches of the tibial nerve (medial plantar nerve and lateral plantar nerve) and supplied by medial and lateral plantar arteries

Diabetic retinopathy

Aprox 1/6 of all cases of acquired blindness Vessels develop over the retina
