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.
This quiz covers the internal structure of the skull and brain, including sinuses, nerves, and blood vessels.
