Axial vs Appendicular Skeleton
Axial skeleton - bones such as the skull, ribs and vertebrae that form a sort of main vertical axis. Appendicular - Everything else
Diaphysis
Bone shaft
Epiphysis
Bone end. Covered with articular cartilage.
Cartilage
Resilient, semi-rigid form of connective tissue that reduces friction and absorbs shock in synovial joints. (meniscus)
Metaphysis
Where the Diaphysis and Epiphysis meet
Medullary Cavity
The space inside the Diaphysis, containing marrow
Endosteum
Lining of the Medullary Cavity containing cells necessary for bone development
Periosteum
Membrane covering the surface of bones except at the articular surfaces. Serves as a point of attachment for ligaments and tendons. Critical for bone growth, repair, and nutrition
Articular
Relating to joints
Compact Bone
Dense bone, forming the external layer of all bones and providing support for weight bearing
Cancellous Bone
Spongy bone, provides strength against stress
Five bone types
Long, Short, Flat, Irregular, Sesamoid
Ligaments
Tissues anchoring bone to bone
Synarthrodial Joints
Joints that don’t move
Synovial (Diarthrodial) Joint
Most common type of joint. Enclosed by joint capsule, lined with synovial membrane, filled with fluid, covered with cartilage.
Amphiarthrodial Joints
Joints with limited movement that are held together by ligaments or fibrocartilage
Synovial Membrane
Produces synovial fluid which lubricates the joint to reduce friction
Arthrodial (Plane) Joint
Synovial joint. Gliding and sliding movements. (carpal bones)
Ginglymus (Hinge) Joint
Synovial joint. Uniaxial movements (elbow and knee)
Condyloid (Ellipsoidal) Joint
Synovial joint. Biaxial. (wrist)
Sellar (Saddle) Joint
Synovial joint. Unique joint that permits movements in all planes, including opposition. (thumb)
Enarthrodial (Ball-and-Socket) Joint
Synovial Joint. Multiaxial joint that permits movements in all directions. (shoulder, hip)
Trochoidal (Pivot) Joint
Synovial joint. Uniaxial joint that permits limited rotation (proximal radioulnar, neck)
Open Chain Movement
Joint movement in which the distal segment of the joint is moving (leg extension machine exercise)
Closed Chain Movement
Joint movement in which the distal segment of the joint is fixed (standing squats)
Open Pack Position
Joint position when there is the most looseness
Closed Pack Position
Joint position when there is the most tightness
Range of Motion (ROM)
Degree of movement of a joint.
Hypermobile Joints
Joints with excessive ROM
Hypomobile Joints
