dpt anatomy - head and neck 1

pterion

• intersection of 4 bones (area of weakness)

• clinical significance → likely to cause epidermal hematoma

• Frontal squama (Front part of forehead)

• superciliary arch (eyebrows)

• glabella (depression between eyebrows)

• frontal eminences (rounded elevations)

• supraorbital foramen (for supraorbital vessels and nerves)

what go through supraorbital foramen/notch

supraorbital nerves and vessels

• Superior/inferior temporal lines (where temporalis muscle attaches superiorly)

• Sagittal suture (b/w parietal bones) not on here :(

• Lambdoid suture (b/w parietals and occipital bone)

• Pterion (junction of temporal, parietal, frontal, and sphenoid bones) – weak region, vulnerable to trauma (epidural hematoma)

• coronal suture (b/w frontal and parietals)

  

dorsum sellae (body) (back of the saddle)

posterior sphenoid

sella turcica (part of sphenoid body) → saddle looking

posterior superior sphenoid

hypophyseal fossa (in center of sella turcica…holds pituitary gland)

greater wing of sphenoid

lesser wing of sphenoid
