Study Notes

Course material presented by Prof. Amjad Al-Shatarat, Department of Biomedical Sciences, Aqaba Medical Sciences University, 2024.

Shoulder Girdle

Composed of the clavicle and scapula.
The clavicle has two ends: acromial (lateral) and sternal (medial).
The clavicle articulates medially with the manubrium of the sternum and laterally with the acromion of the scapula.

Scapula

Contains the acromion process, coracoid process, and glenoid cavity.
The glenoid cavity articulates with the head of the humerus to form the glenohumeral (shoulder) joint.

Bones of the Upper Limbs

Each upper limb consists of the humerus, radius, ulna, carpals, metacarpals, and phalanges.

Humerus

The bone of the arm.
Has an upper end, lower end, and a shaft.
- The upper end includes the head, anatomical neck, surgical neck, greater tubercle, and lesser tubercle.
- The lower end includes the medial epicondyle, lateral epicondyle, capitulum, and trochlea.

Forearm Bones (Ulna and Radius)

The ulna is medial, and the radius is lateral in the forearm.
- The ulna has an olecranon, trochlear notch, coronoid process, and ulnar tuberosity.
- The radius has a head, neck, and radial tuberosity.

Wrist Bones (Carpals)

The carpals are arranged in two rows: proximal and distal.
The proximal row consists of scaphoid, lunate, triquetrum, and pisiform.
The distal row consists of trapezium, trapezoid, capitate, and hamate.
These bones facilitate precise hand movements.

Hand Bones (Metacarpals and Phalanges)

The metacarpals lead to the phalanges (finger bones).

Hip Bone

Composed of three bones: ilium, ischium, and pubis.
Triradiate cartilage joins these bones at the acetabulum.
The hip bones articulate with the sacrum posteriorly, and with each other anteriorly at the symphysis pubis.

Femur

The thigh bone.
Has an upper end (head, neck, greater trochanter, lesser trochanter), a shaft/body, and a lower end (medial and lateral condyles, medial and lateral epicondyles).

Patella

A triangular sesamoid bone within the patellar ligament.

Tibia

The shin bone, with an upper end (lateral and medial condyles, tibial tuberosity), a shaft/body, and a lower end (medial malleolus).

Fibula

Lateral bone of the lower leg (has a head, neck, and lateral malleolus).

Foot Bones (Tarsals, Metatarsals, Phalanges)

Tarsals include calcaneus, talus, cuboid, navicular and cuneiform bones
Metatarsals lead to the phalanges (toe bones).

Foot Arches

The arches of the foot distribute body weight effectively.
The arches are usually fully developed by age 12 or 13.
- The key arches are medial longitudinal, lateral longitudinal, and transverse.

Flat Foot

A condition where the medial longitudinal arch is flattened or collapsed.
Causes can be congenital or acquired.
