Study Notes
Skull and Cranium Overview
- The skull, or cranium, consists of 22 individual bones, providing structure, support for the face, and protection for the brain.
- Divided into two sections:
- Neurocranium: Cranial bones
- Viscerocranium: Facial bones
Glossary of Terms
- Internal: Inner part
- External: Outer part
- Articulate: Joining/touching
- Foramen: Opening for blood/nerve passage
- Fossa: Shallow depression
- Process: Large distinctive bone projection
- Canal: Tunnel through bone
- Tubercle: Small elevation on a bone
- Eminence: Bone elevation
- Tuberosity: Bulbous bone feature
- Margin: Edge of a bone
Neurocranium Functions
- Protects the brain and surrounding structures.
- Provides attachment sites for facial expression and mastication muscles.
- Forms the framework for cranial and orbital cavities.
Brain Lobes
- The cerebrum is divided into four lobes:
- Frontal Lobe: Involved in personality, behaviour, emotions, judgement, planning, problem-solving, speech, and body movement.
- Parietal Lobe: Processes language, sensory touch, pain, temperature, and spatial perception.
- Occipital Lobe: Interprets visual signals including color and movement.
- Temporal Lobe: Handles language comprehension, memory, and auditory processing.
Broca's and Wernicke's Areas
- Broca's Area: Located in the left frontal lobe; damage results in difficulty speaking and writing, while understanding language remains intact (Broca's aphasia).
- Wernicke's Area: Located in the left temporal lobe; damage leads to fluent but nonsensical speech, making it difficult for the individual to understand spoken language (Wernicke's aphasia).
Cranial Bone Joints – Sutures
- Sutures are fixed, immovable joints made of collagen that strengthen the skull over time.
- Major cranial sutures include:
- Coronal Suture: Joins frontal and parietal bones.
- Sagittal Suture: Joins the two parietal bones at the midline.
- Lambdoid Suture: Joins parietal bones with the occipital bone.
- Squamosal Suture: Joins squamous part of temporal bone with parietal bones.
- Metopic Suture (Frontal Suture): Unites the two frontal bones, when present.
Etymology of Sutures
- Coronal: Derived from 'crown' in Latin.
- Sagittal: Pertains to an arrow-like structure or division.
- Lambdoid: Comes from Greek, symbolizing an upside-down "V."
- Squamosal: Relates to flat/broad surfaces, specifically, the squamous portion of the temporal bone.
