1 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull HEAD/NECK I: Introduction—The Skull Head function brainstorm Sensory/Motor Targets Overview: Head/Neck I-IV The two-oval skull Major features of the skull The base of the skull –The developmental view –The holes-out view

2 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull What all does the head do? [brainstorm] SensesFoodBreatheSecreteBrainOther

3 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull Nerve “targets” in head SENSORY SpecialGeneral MOTOR MusclesGlands

4 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull Overview Head/Neck I-IV Head I: Skull—a framework to hang on –Overall organization of skull –Base of the skull—the hard part Developmental view Cranial nerves out (to “targets”) Head II: Throat targets Head III: Special Sense targets Head IV: Cranial nerves in depth

5 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull Overall skull organization Cerebral Hemisphere Cerebellum Neurocranium Base of skull Middle ear Jaw Throat

6 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull Major features of the skull Mastoid process External auditory/ acoustic meatus (ear opening) Ear drum Hyoid bone Epiglottis Thryroid cartilage Cricoid cartilage Tracheal rings

7 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull M&M, Fig. 7.3

8 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull Major features of the skull Zygomatic arch Ethmoid Orbit Nasal passage External nasal aperture Internal nasal aperture

9 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull M&M, Fig. 7.2

10 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull Base of the skull—a developmental view Dermal bones in neurocranium Chondral bone at base of skull –Olfactory capsule (part of ethmoid) –Optic capsule (part of sphenoid) –Otic capsule (part of temporal –Occipital bone (from somites like C-verts)

11 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull Base of the skull—cranial nerves out Ethmoid (olfactory) I. Olfactory Sphenoid (optic) II. Optic III. Oculomotor IV. Trochlear VI. Abducens Temporal (otic) VIII. Acoustic/Auditory/ Vestibulocochlear Face/Jaws V. Trigeminal VII. Facial Throat (rest of body) IX Glossopharyngeal X. Vagus XI. Spinal Accessory XII. Hypoglosal

12 Human Anatomy, Frolich, Head/Neck I: Introduction—the Skull

13 What’s ahead? Throat (pharynx) targets: Head/Neck II Special Sensory targets: Head/Neck III Back to cranial nerves: Head/Neck IV
