What covers the cranial vault?
What covers the cranial vault?
The scalp is the outer layer of the head, covering the bones of the skull known as the cranial vault.
Facial muscles: What's their job?
Facial muscles: What's their job?
Facial muscles are responsible for creating facial expressions, allowing us to smile, frown, and show various emotions.
Trigeminal Nerve (CN V)
Trigeminal Nerve (CN V)
The trigeminal nerve is a major nerve responsible for sensory innervation of the face, meaning it carries feeling from the face to the brain.

Study Notes
Structures Covered by the Scalp
- The scalp covers the skull and is composed of five layers: skin, subcutaneous tissue, aponeurosis (galea aponeurotica), loose connective tissue, and pericranium.
Function of Muscles of Facial Expression
- Muscles of facial expression are responsible for various facial movements, including smiling, frowning, raising eyebrows, and closing the eyes.
- These muscles are innervated by the facial nerve (CN VII).
Learning Objectives of the N&N II Section
- The N&N II section aims to teach about the anatomy and function of the head and neck, focusing on key structures and their clinical significance.
- This section delves into the nervous system, vascular system, and musculoskeletal system of the head and neck region.
Nerves Involved in Sensory Innervation of the Face
- The trigeminal nerve (CN V) plays a vital role in sensory innervation of the face.
- Its three branches, the ophthalmic, maxillary, and mandibular nerves, provide sensory input to different areas of the face.
Risks Associated with Scalp Injuries and Lacerations
- Scalp injuries and lacerations can lead to bleeding, infection, and potential damage to underlying structures.
- Risks can include injury to blood vessels, nerves, and even the skull.
- In severe cases, scalp injuries can lead to complications such as cerebrospinal fluid leaks.
