Study Notes

Neurocranium

Comprises the bones that enclose and protect the brain
Includes the calvarium (skullcap) and basis cranii (cranial base)

Skull Bones

Os frontale (Frontal Bone):
- Forms the forehead and part of the eye sockets (orbital parts)
- Also includes the nasal part (forming part of the nose)
Ossa parietalia (Parietal Bones): (2)
- Form the sides and top of the cranium
- Connected to the frontal bone by the coronal suture (crown suture)
- Connected to the occipital bone by the lambdoid suture
- Connected to the temporal bones by the squamous sutures
- Features include the following:
  - Superior and inferior temporal lines
  - Parietal tubercles
  - Parietal foramina
Os occipitale (Occipital Bone):
- Forms the back and base of the skull
- Contains the foramen magnum (large opening for the spinal cord)
- Includes the pars squamosa, pars basilaris, partes laterales.
- Features include the following:
  - External occipital protuberance
  - Superior and inferior nuchal lines
  - Foramen magnum (big hole)
Ossa temporalia (Temporal Bones): (2)
- Lie below the parietal bones,
- Contains structures related to the ear
- Divided into parts:
  - Pars squamosa (squamous part): forms part of the temporal bone
  - Pars petrosa (petrous part): forms part of the cranial base
  - Pars mastoidea (mastoid part): filled with air spaces (mastoid cells)
  - Pars tympanica(tympanic part): forms part of the bony structure of the ear
  - Features include:
    - Zygomatic process
    - Styloid process
    - Mastoid process
    - External acoustic meatus
    - Internal acoustic meatus
    - Mandibular fossa and articular tubercle
Os sphenoidale (Sphenoid Bone):
- Forms part of the base of the cranium and the eye sockets.
- Features include:
  - Body
  - Greater and lesser wings
  - Pterygoid processes
  - Sella turcica (Turkish saddle): houses the pituitary gland
  - Optic canals
  - Foramen rotundum, ovale, spinosum
Sutures:
- Coronal suture (crown suture), joining the frontal and parietal bones
- Lambdoid suture, joining the parietal and occipital bones
- Squamous suture, joining the parietal and temporal bones.

Sphenoid Bone Details

Corpus ossis sphenoidalis (Body):
- Contains the sella turcica (pituitary fossa)
- Features conchae, crista,rostrum, sinus
Alae minores (Lesser Wings):
- Optic foramina
  - Passages for the optic nerves
- Processes clinoidei anteriores
Alae majores (Greater Wings):
- Several foramina (openings)
  - Foramen rotundum, ovale
Processus pterygoidei (Pterygoid Processes): –Paired
- Pterygoid fossa
- Hamulus pterygoideus

Other Important Structures

Foramina: Various openings in the skull bones.
Canals: Passages through the skull bones.
Processes: Projections of bone.
Sutures: Immovable joints between skull bones.
