Study Notes

Skull and Brain

The internal occipital protuberance is the confluence of sinuses.
The superior sagittal, transverse, occipital, and straight sinuses are all located in the skull.

Foramen Ovale

The mandibular nerve (V3) traverses through the foramen ovale.
The accessory meningeal artery passes through the foramen ovale.
The lesser petrosal nerve travels through the foramen ovale.
The emissary vein and otic ganglion also pass through the foramen ovale.

Sympathetic Innervation

Sympathetic innervation causes the eye to adduct and deviate to the right.
It also leads to an inability to abduct the eye.

Nerves

The lingual nerve carries general sensory, taste, parasympathetic, and visceral motor information.

Muscles of Mastication

The pinned muscle of mastication causes movement in the carotid triangle.
The common carotid artery, internal jugular vein, vagus nerve, and hypoglossal nerve are all located in the carotid triangle.

Pelvis and Urinary System

The muscle that inserts into the superior and/or inferior vesicle artery is located in the bladder.

Female Reproductive System

The region bounded by the two pins is the cervical canal/cervix.
The mesosalpinx is an area of the broad ligament.

Blood Supply

The artery that supplies blood to the erectile tissue in the linea aspera is not specified.

Lower Limb

The femoral nerve supplies muscles in the femoral triangle, including the quadriceps, pectineus, sartorius, and iliacus.
The femoral nerve is responsible for adduction of the thigh at the hip joint.
