Study Notes
Coxal Bone Components
- Ilum, ischium, and pubis fuse to form the coxal bone.
- Ischium is known as the sit-down bone of the coxal bone.
- Pubic symphysis is the junction where the coxal bones join anteriorly.
Coxal Bone Features
- Iliac crest is the superiormost margin of the coxal bone.
- Acetabulum is the deep socket in the coxal bone that receives the head of the femur.
- Sacroiliac joint serves as the connection between the axial skeleton and the pelvic girdle.
Knee Joint Structures
- Femur and tibia are the bones that form the knee joint.
- Tibial tuberosity is the site where the patellar ligament attaches.
- Patella is commonly referred to as the kneecap.
- Tibia, also known as the shinbone, carries the weight of the leg.
Ankle and Foot Bones
- Medial malleolus is the projection on the medial side of the ankle.
- Lateral malleolus is the projection on the lateral side of the ankle.
- Calcaneus is the largest tarsal bone, commonly referred to as the heel.
- Tarsals include the medial cuneiform, intermediate cuneiform, lateral cuneiform, cuboid, talus, calcaneus, and navicular.
- Metatarsals form the instep of the foot.
Hip Bone Anatomy
- Obturator foramen is an opening in the hip bone formed by the pubic and ischial rami.
- Gluteal tuberosity, along with greater and lesser trochanters, are sites for muscle attachment on the proximal femur.
- Talus articulates with the tibia and sits on top of the calcaneus.
Upper Limb Structure
- Carpals are wrist bones summarized as: Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate.
- Deltoid tuberosity is a raised area on the lateral surface of the humerus for deltoid muscle attachment.
- Acromion is the part of the scapula that connects to the clavicle.
- Humerus is the long bone of the arm.
Girdles and Forearm
- Shoulder girdle consists of clavicle and scapula.
- Forearm bones include the radius and ulna.
- Scapula is unattached to the axial skeleton.
- Clavicle transmits forces to the bony thorax.
Shoulder Structure
- Glenoid cavity is the depression in the scapula that articulates with the humerus.
- Coracoid process is located above the glenoid cavity, allowing muscle attachment.
Humerus Features
- Trochlea is the distal condyle of the humerus that articulates with the ulna.
- Ulna is the medial bone of the forearm in the anatomical position.
- Capitulum is the rounded knob on the humerus that adjoins the radius.
- Coronoid fossa is an anterior depression that receives part of the ulna when the forearm is flexed.
Hand Anatomy
- Phalanges are the bones of the fingers and toes, totaling 14.
- Metacarpals form the knuckles in the hand.
Rib Types and Vertebral Column
- True ribs (7 pairs) attach directly to the sternum via individual costal cartilages.
- False ribs (5 pairs) attach to the sternum indirectly (ribs 8-10).
- Floating ribs (last 4 pairs) have no anterior attachments.
- Cervical vertebrae consist of C1-C7, with C1 known as atlas (carries the skull) and C2 known as axis.
- Thoracic vertebrae are T1-T12, which articulate with the ribs.
- Lumbar vertebrae (L1-L5) support most weight due to their massive bodies.
- Sacrum comprises 5 fused vertebrae, shaping the posterior wall of the pelvis.
