Study Notes
Skull and Bones
- All skull bones, except the mandible, are united by immovable sutures.
- The hyoid bone is unique for not articulating with any other bone in the body.
- The maxilla is the largest and strongest bone of the face.
- The radius is the lateral bone of the forearm in the anatomical position.
- Costal cartilages connect most ribs to the sternum.
Functions of the Skeletal System
- Functions include blood cell formation, calcium storage, and movement.
- All listed options are indeed functions of the skeletal system.
Spinal and Cranial Anatomy
- Lordosis does not affect the thoracic vertebrae.
- The frontal bone connects to the parietal bone via the coronal suture, not the sagittal suture.
Fetal Skull Features
- Membranous areas between fetal cranial bones are called fontanelles.
Cranial and Facial Bones
- The lacrimal bone is a facial bone and not part of the cranium.
- The sagittal suture is located between the two parietal bones.
Unpaired and Paired Bones
- The frontal bone is the only unpaired cranial bone.
Sphenoid Bone Characteristics
- The sphenoid bone spans the width of the cranial floor and contains the sphenoidal sinuses.
- The sella turcica, a depression in the sphenoid bone, houses the pituitary gland.
- The lesser wings of the sphenoid bone contain the optic canal, which transmits the optic nerve.
Foramina and Nerves
- The foramen rotundum serves as a passageway for a branch of the trigeminal nerve (CN V).
- The sella turcica is described as a depression in the sphenoid bone.
Sinuses
- The sphenoid bone is associated with paired sphenoidal sinuses, highlighting its role in cranial structure.
