Study Notes
Skull and Cranial Cavity Module 202 - Lecture 1 Summary
- Module 202 Anatomy consists of 4 lectures and 4 DR sessions.
- The lectures cover topics such as the skull, cranial cavity, face, temporal and infratemporal fossa, the orbit and nasal cavity, and the neck and oral cavity.
- There are additional optional DR sessions for brain removal and face and neck dissection.
- Students can redeem a free Complete Anatomy Student licence for the module.
- Slido Q&A is available for students to post anonymous anatomy-related questions.
- The scalp is composed of skin, connective tissue, aponeurosis, loose connective tissue, and periosteum.
- Lacerations to the scalp bleed profusely due to the inability of the dense connective tissue layer to retract.
- The skull is divided into the neurocranium and viscerocranium, which join at sutures.
- The neurocranium includes bones such as the frontal and ethmoid bones.
- The viscerocranium includes bones such as the palatine, zygoma, and mandible.
- The skull contains cranial foramina through which veins, cranial nerves, and arteries enter and exit.
- The blood supply to the head, neck, and brain is provided by the internal carotid artery, vertebral artery, and the cerebral arterial circle (Circle of Willis).
