Study Notes
Coxal Bone Components
- Coxal bone consists of three fused bones: ilium, ischium, and pubis.
- Acetabulum serves as the deep socket in the hip bone receiving the head of the femur.
Ischium and Sitting
- The ischium is responsible for bearing the body's weight when in a sitting position.
Pubic Symphysis
- The pubic symphysis is the joint where both coxal bones connect anteriorly.
Iliac Crest
- The iliac crest is the upper edge of the ilium bones, forming a significant landmark on the hip.
Femur
- The longest bone in the human body, the femur, connects with the coxal bone at the hip joint.
Leg Bones
- The leg comprises two primary bones: the medial tibia and the lateral fibula.
Knee Joint
- The knee joint is formed by the femur, patella, and tibia, facilitating knee movement.
Patella
- Commonly known as the kneecap, the patella provides protection and stability to the knee joint.
Medial and Lateral Malleolus
- The medial malleolus is the distal projection on the tibia's medial side; the lateral malleolus is the projection on the fibula, forming the outer ankle.
Tarsals and Metatarsals
- The tarsals consist of bones in the ankle, while the metatarsals form the instep of the foot.
Obturator Foramen
- The obturator foramen is an opening in the coxal bone created by the rami of the pubis and ischium.
Talus
- The talus is the tarsal bone that articulates with the tibia, critical for ankle movement.
Pelvic Girdle
- The pelvic girdle is formed by the articulation of the hip bones with the sacrum, providing structural support.
Phalanges
- Phalanges are the bones present in both the hand and foot, essential for digit movement.
Periosteum
- The periosteum is the tough, fibrous connective tissue covering that protects and nourishes bones.
Fusion of Coxal Bone
- The acetabulum represents the point where the three bones of the coxal bone fuse together.
Fetal Bone Development
- In fetal development, the long bones are initially constructed from hyaline cartilage before ossification occurs.
Foramen Magnum
- The largest foramen in the skull is the foramen magnum, which allows spinal cord passage.
