Chapter 8 Flashcards
Axial & Appendicular Skeleton
axial skeleton is composed of the bones along
the central axis of the body.
head, neck, trunk
The appendicular skeleton is the skeleton of
the upper and lower limbs; the appendages. It also contains the girdles, bones that keep the limbs into place. Pelvic is for lower limbs, pectoral for upper limbs.
Bone markings
are distinctive surface features that characterize each bone in the body.
Articulating surfaces are
generally smooth areas between adjacent bones.
Depressions
provide space for a bony articulation, muscular structure, or other body component.
Projections
mark the points where muscles, tendons, and ligaments attach.
Openings and spaces
indicate sites for passageways for vessels and nerves.
Fontanelles
are regions of dense regular connective tissue interconnected with the cranial bones. Infantile cranial bones are not large enough to fully enclose the brain, so these regions provide extra protection.
Herniated disc
occurs when the nucleus pulposus protrudes through the anulus fibrosus, creating a bulging of the disc which can cause compression of the spinal cord, nerves of the spinal cord, or both.
Bunion is
a localized swelling of the metatarsophalangeal joint. These are caused by shoes that are too tight and are the most common foot problem.
Pes planus is
where the medial longitudinal arch is flattened and the entire sole of the foot touches the ground. Often caused by excessive weight, issues with posture, or weakened supportive tissue.
Pes cavus is
excessively high lateral longitudinal arches.
Talipes equinovarus
is when the feet are permanently inverted from lack of room to grow during gestation.
