Study Notes

Scapula and Clavicle

Scapula: Also known as the shoulder blade, essential for upper limb movement.
Acromion: The bony process on the scapula, forming part of the shoulder.
Coracoid process: A small hook-like structure on the scapula for muscle attachment.
Glenoid cavity: The shallow depression in the scapula that articulates with the head of the humerus.
Spine: A prominent ridge on the posterior surface of the scapula.

Humerus

Humerus: The long bone of the upper arm, connecting shoulder to elbow.
Lateral epicondyle: Outer bony prominence of the humerus, serves as an attachment for forearm muscles.
Medial epicondyle: Inner bony prominence of the humerus, also for muscle attachment.

Forearm

Ulna: One of the two bones of the forearm, located on the inner side.
Radius: The other forearm bone, located on the outer side.
Olecranon: The bony prominence at the elbow, part of the ulna.
Trochlear notch: The indentation in the ulna that fits over the humerus at the elbow.
Styloid process (ulna and radius): Bony projections on the wrist end of each bone.

Carpal Bones

Wrist (carpals): Composed of 8 small bones, forming the wrist joint.
Proximal carpal bones: First row of carpal bones closest to the forearm.

Pelvic Girdle

Ilium: Large, fan-shaped bone forming the upper part of the pelvis.
Ischium: The lower, posterior part of the pelvic bone.
Pubis: The front portion of the pelvic bone.
Acetabulum: The socket formed by the fusion of ilium, ischium, and pubis for hip joint articulation.
Obturator foramen: Large hole in the pelvis formed by ischium and pubis for ligament and nerve passage.
Pubic symphysis: Joint where the left and right pubic bones meet, made of hyaline cartilage.

Femur and Patella

Femur: The thigh bone, the longest bone in the body.
Head of femur: Round part of the femur that fits into the acetabulum.
Lateral and medial epicondyles: Bony projections on either side of the femur's distal end for muscle attachment.
Lateral and medial condyles: Smooth surfaces at the distal end of the femur that articulate with the tibia.
Patella: The kneecap, protects the knee joint.

Lower Leg

Tibia: The larger and stronger bone of the lower leg, also known as the shinbone.
Fibula: The thinner bone of the lower leg, located alongside the tibia.
Tibial tuberosity: A prominent bump on the tibia where knee ligaments attach.

Ankle and Foot

Talus: The bone that sits above the heel bones, connecting the foot to the leg.
Calcaneus: The heel bone, largest bone in the foot.
Navicular bone: A small bone located in the ankle, situated between the talus and the cuneiform bones.
Cuboid bone: A cube-shaped bone on the lateral side of the foot.
Cuneiform bones: Three bones at the base of the foot that articulate with the navicular.

Digits

Metacarpals: Five bones in the middle part of the hand.
Phalanges: The bones of the fingers, consisting of proximal, middle, and distal sections.
Distal, medial, and proximal phalanx: Terms identifying the locations of finger bones, with the distal being farthest from the hand.

Joint Structure and End Points

Distal end of humerus: All structures and attachments at the bottom of the humerus.
Proximal end of humerus: All structures and attachments at the top of the humerus.
Distal and proximal ends of tibia and fibula: Bottom and top ends of the lower leg bones, respectively.
