Study Notes
Temporal Bone
- The petrous part of the temporal bone houses the middle and inner ear cavities.
- The styloid process, located in the tympanic part of the temporal bone, serves as an attachment point for muscles and ligaments involved in tongue movement and swallowing.
- The mastoid process is located posterior to the tympanic part of the temporal bone.
- The internal acoustic meatus in the petrous part of the temporal bone allows passage of the vestibulocochlear nerve (CN VIII), which carries signals for hearing and balance.
Ear Function
- The ear's main function is auditory perception (hearing) and equilibrium (balance).
Sphenoid Bone
- The sella turcica, a saddle-shaped depression in the sphenoid bone, houses the pituitary gland.
Hard Palate
- The palatine bones contribute to the formation of the hard palate.
Oral Cavity
- The hard palate, formed by the palatine and maxillary bones, separates the nasal cavity and nasopharynx from the mouth.
Foramen
- The jugular foramen, located at the base of the skull, allows passage of the internal jugular vein, a major blood vessel draining the head and neck.
Temporal Bone and Mandible Articulation
- The temporomandibular joint (TMJ) is located at the interface of the temporal bone and the mandible, enabling jaw movement for speaking, chewing, and swallowing.
