Study Notes
Long Bone Parts
- Epiphysis: The end of a long bone
- Articular Cartilage: A smooth, hyaline cartilage covering the epiphysis, facilitating joint movement.
- Red Bone Marrow: Found within spongy bone, responsible for blood cell production (hematopoietic tissue).
- Epiphyseal Line: A remnant of the epiphyseal plate (growth plate), indicating the closure of bone growth.
- Spongy Bone: A porous bone with a lattice-like structure, found mainly in the epiphysis.
- Metaphysis: The region between the epiphysis and diaphysis
- Diaphysis: The shaft of a long bone
- Periosteum: A tough, fibrous membrane covering the outer surface of the bone.
- Endosteum: A thin membrane lining the medullary cavity.
- Medullary Cavity: The hollow space within the diaphysis.
- Yellow Bone Marrow: Fatty tissue filling the medullary cavity in adults. Primarily composed of fat
- Compact Bone: The dense, hard outer layer of bone.
Skeletal Landmarks

Iliac Crest: Upper border of the ilium bone.
-
Lateral Malleolus: Bony prominence on the lateral side of the ankle.
-
Greater Trochanter: Large bony projection on the lateral hip bone.
-
Occipital Bone: Bone forming the back and base of the skull.
-
Olecranon Process: Bony projection of the ulna.
-
Calcaneus: Heel bone of the foot.
-
Patella: Kneecap.
-
Inferior Angle of Scapula: Bottom edge of the shoulder blade.
-
Mastoid Process: Projection on the temporal bone behind the ear.
-
Acromion Process: The outermost projection of the scapula.
-

-
Tibial Tuberosity: Roughened area on the anterior surface of the tibia.
-
Head of Radius: Proximal end of the radius bone.
-
Anterior Superior Iliac Spine: Prominent bony point on the hip bone.
-
Ischial Tuberosity: The roughened, inferior part of the ischium bone.
-
Glenoid Fossa: Cavity in the scapula that articulates with the humerus.
-
Spinous Process: Projection on a vertebra.
-
Lateral Humeral Epicondyle: Bony projection on the lateral aspect of the humerus.
-
Xiphoid Process: Inferior portion of the sternum.
-
Crest of Tibia: Superior border of the tibia.
Synovial Joint
- Anterior Cruciate Ligament: Ligament within the knee giving stability to the joint.
- Articular Cartilage: Aids with smooth movement in joints.
- Bursa: Fluid-filled sac that cushions and reduces friction around joints.
- Fat Pad: Cushions the knee joint.
- Fibrous Joint Capsule: Outer layer of the joint cavity composed of fibrous connective tissue
- Menisci: C-shaped fibrocartilaginous pads that cushion and stabilize the knee joint.
- Patella: Kneecap.
- Patellar Ligament: Ligament connecting the kneecap to the tibia.
- Synovial Fluid: Lubricating fluid within the joint cavity.
- Synovial Membrane: Inner lining of the joint capsule, secreting synovial fluid.
