Study Notes
Bone Classification and Articulation
- The fibula is not the major weight-bearing bone of the leg; that role is primarily fulfilled by the tibia.
- Most skull bones, excluding the mandible, are immovable and joined by sutures.
- The frontal bone does not articulate with the parietal bone via the sagittal suture; it connects with the parietal via the coronal suture.
- Mastoid sinuses are susceptible to infections rather than being free from them.
Vertebral Column and Body Weight
- The vertebral column is stabilized mainly by anterior and posterior longitudinal ligaments.
- Body weight is predominantly supported by the talus and calcaneus bones in the foot.
Fractures and Joint Stability
- The anatomical neck of the humerus is not the most common fracture site; the surgical neck is more prone to fractures.
- The scapula is commonly referred to as the shoulder blade, not the collarbone.
- The shoulder joint's shallow socket does not enhance stability but allows greater mobility of the humerus.
Rib and Pelvic Structure
- Costal cartilages connect most ribs to the sternum for structural integrity.
- The tubercle of a rib articulates with the transverse process of vertebrae.
- In women of childbearing age, the true pelvis dimensions are critical for childbearing.
- Vertebrochondral ribs attach to each other before connecting to the sternum.
Anatomy of the Skeleton
- The lateral bone of the forearm, in the anatomical position, is the radius.
- The vomer bone contributes to the formation of the nasal septum.
- There are a total of seven cervical, twelve thoracic, and five lumbar vertebrae, confirming the typical vertebral count.
- Lordosis primarily affects the lumbar, not thoracic vertebrae.
Vertebral Characteristics
- Not all vertebrae possess transverse foramina; this feature is specific to cervical vertebrae.
- The dens, or odontoid process, is specific to the axis vertebra and does not articulate with it.
- The pituitary gland is housed in the sella turcica of the sphenoid bone, not in the temporal bone.
Pelvic Anatomy and Development
- The ischium articulates with both the ilium and pubis, forming part of the pelvic structure.
- The ilium forms the largest portion of the coxal bone, making it essential for pelvic stability.
Skull Development
- The membranous areas between cranial bones in a fetal skull are known as fontanelles.
- The ethmoid bone consists of several structures but does not include the inferior nasal concha.
Special Bones and Articulations
- The hyoid bone is unique as it does not articulate with any other bone, serving as an anchor point for tongue muscles.
- The sagittal suture connects the two parietal bones of the skull.
- The anterior ligament of the vertebral column prevents hyperextension while providing support and maintaining disc position.
