Study Notes
Bone Anatomy and Classification
- Condyles are not restricted to the axial skeleton; they can be found in other regions.
- Trochanters are unique to the femur, distinguishing it from other bones.
- The mastoid process on the temporal bone can be palpated externally on a living person.
- Healthy paranasal sinuses are air-filled and not filled with mucus.
Cranial and Facial Bones
- The optic canal is located in the sphenoid bone, crucial for optic nerve passage.
- Sutures connect cranial, facial, and sacral bones, forming immovable joints in the skull.
- The atlantoaxial joint, between C1 and C2 vertebrae, allows for head rotation.
- All ribs do not articulate with the sternum; only true ribs connect directly.
Ribs and Gender Differences
- Men and women have the same number of ribs, with no significant difference in rib count.
Palpable Bone Features
- The radius's styloid process can be palpated near the base of the thumb.
- The pubic symphysis is a palpable structure above the genitalia.
Skeletal Structure
- The average adult skeleton contains 206 bones.
- The scapula is part of the appendicular skeleton and not included in the axial skeleton.
- A condyle is a rounded knob that articulates with another bone.
Bone Terminology
- Any bony prominence is classified as a process, which can include epicondyles and tubercles.
- Some separate bones in a child fuse with age, resulting in fewer bones in adults.
Sesamoid Bones and Bone Passage
- Sesamoid bones form within tendons due to stress, enhancing movement and joint function.
- Foramen refers to any hole through a bone allowing passage for nerves and blood vessels.
Appendicular vs. Axial Skeleton
- Ethmoid bone does not belong to the appendicular skeleton, as it is part of the axial skeleton.
- Sutures are the primary joints connecting most skull bones.
Sinus Locations
- Temporal bone lacks sinuses, which are present in other skull bones like the sphenoid, frontal, and maxilla.
Bone Characteristics
- The temporal bone features processes such as the zygomatic process, mastoid process, and external acoustic meatus, but not the sella turcica.
- Parietal bones are not considered facial bones; they are part of the cranial structure.
Sella Turcica and Bone Pairing
- The sella turcica, located in the sphenoid bone, houses the pituitary gland.
- Ethmoid bone is a single, unpaired bone in the skull, differentiating it from paired bones like the parietals.
Skull Sutures
- Squamous suture separates the temporal and parietal bones, whereas coronal and lambdoid sutures connect different cranial structures.
