Mastoid process: behind external acoustic meatus stylomastoid foramen, facial nerve carotid canal emerges through here, internal carotid artery. With vertebral arteries are major blood supply to brain doesn"t follow straight path through canal internal carotid comes from neck: turns and goes over foramen lacerum covered in cartilarge carotid comes up and branches off all foramen know location know whats in that area. Where are they going function of all cranial nerves origin where does it start insertion where is it going to agonist prime mover of a joint antagonist muscle that opposes that synergists help with that action. Most muscles cross a joint: move skeleton facial expression don"t cross a joint, move skin different shapes of muscles, circular muscle surrounds mouth orbicularis oris boney attachment, but attachment is meshed in with skin, parallel muscles sternocleidomastoid origin at top, attachment at bottom, convergent, pennate fusiform bicep muscle.
