Study Notes
Human Skeletal System Overview
- The matrix of cartilage contains collagen fibers and is located between the tips of ribs and sternum, covering bone surfaces at synovial joints, and supporting various parts of the respiratory system.
- Elastic cartilage contains collagen and elastic fibers and is found in the auricle of the external ear, epiglottis, auditory canal, and cuneiform cartilages of the larynx.
- Fibrous cartilage contains a limited number of cells and ground substance amidst a substantial amount of collagen fibers and is located in pads within the knee joint, between pubic bones of the pelvis, and intervertebral discs.
- Ossification is the process of replacing other tissues with bone, and it occurs through intramembranous ossification and endochondral ossification.
- Bones are calcified, living connective tissue that forms the majority of the skeleton and serve various functions such as support, protection of vital organs, and calcium and phosphorus reservoirs.
- There are two types of bones: compact bone, which forms the outer shell of all bones and surrounds spongy bone, and spongy bone, which consists of spicules of bone enclosing cavities containing blood-forming cells.
- Bones have two ends, or epiphyses, separated by a tubular diaphysis, and growth in length occurs on both sides of the bone at the epiphyseal plates while growth in thickness occurs in the periosteum.
- Joints are the site where two skeletal elements come together or articulate, and there are two big groups: synovial joints and solid joints.
- Solid joints include fibrous joints, which have restricted mobility, and cartilaginous joints, which have two subtypes: synchondrosis and symphysis.
- Synovial joints are characterized by a layer of hyaline cartilage covering the articulating surfaces, a joint capsule, and additional structures such as articular discs, fat pads, and tendons.
- Synovial joints include gliding (planar) joint, hinge joint, pivot joint, ellipsoid joint, saddle joint, and ball-and-socket joint.
- Gliding (planar) joint is a type of synovial joint characterized by nearly flat articulating surfaces and limited motion.
