Study Notes
Hip Joint and Pelvis
- The hip joint consists of the head of the femur articulating with the acetabulum of the coxal bone.
- The acetabulum is formed by the fusion of the ilium, ischium, and pubis.
- The hip joint is a ball-and-socket joint allowing for a wide range of motion.
- Ligaments (iliofemoral, pubofemoral, ischiofemoral) reinforce the hip joint capsule.
- Muscles surrounding the hip joint (gluteus maximus, medius, minimus, tensor fasciae latae, etc.) produce movement.
- Important ligaments like the sacrospinous and sacrotuberous ligaments stabilize the sacroiliac joint.
- The angle of inclination of the femur differs between males and females.
- Hip rotators are important for rotating the hip inward and outward.
Hip Lateral Rotators
- Muscles that laterally rotate the hip joint include the piriformis, gemellus superior, obturator internus, obturator externus, and quadratus femoris.
- Innervation varies among the muscles
Hip Medial Rotators
- Muscles aiding in medial hip rotation include the gluteus medius and minimus, tensor fasciae latae, and pectineus.
Pelvic Muscles
- Muscles like the iliopsoas, rectus femoris, and sartorius are involved in hip flexion.
Hip Joint Movement
- Hip flexion, extension, abduction, adduction, internal rotation, external rotation, are all possible movements within the hip joint.
- Dislocations can occur in either an anterior or posterior direction.
Knee Joint
- The knee joint is composed of the femur, tibia, and patella.
- The knee is a hinge type of joint allowing primarily for flexion and extension movements.
- Cruciate ligaments and collateral ligaments are essential for stability and movement of the knee joint.
- Menisci are responsible for shock absorption within the knee joint.
- The patellofemoral joint is within the knee region.
- Variations in the knee in terms of angle are: genu varum (bow-legged), and genu valgum (knock-kneed).
Leg Anatomy
- The tibia and fibula comprise the leg's major bones.
- Tibial weight-bearing role is distinguished from the fibula's vestigial nature.
- Muscles within anterior, medial, and posterior compartments are crucial for leg movement.
- Compartment syndrome is a condition that requires understanding of leg structures.
Foot Anatomy
- The foot comprises tarsals, metatarsals, and phalanges.
- The arch of the foot provides support and distributes body weight.
- Ligaments and tendons are responsible for its function.
- Muscles within the foot are classified as dorsal or planter foot muscles.
Ankle Joint
- The ankle joint connects the foot and lower leg.
- Ankle sprains and fractures are common injuries.
- Ligaments are crucial for ankle stability.
- The movement of plantar flexion and dorsiflexion are key functions of the ankle joint.
Nervous System
- The sacral plexus innervates the posterior portion of the thigh and leg.
- The lumbar plexus innervates the anterior thigh and leg.
Thoracic Anatomy
- The thorax (chest) structure includes the ribs, sternum, and thoracic vertebrae.
- The thoracic cavity contains the heart and lungs.
- The diaphragm is a musculotendinous structure that facilitates respiration.
Respiratory System
- The respiratory system involves structures such as the trachea and bronchi.
Heart
- The heart is a vital organ in the body's circulatory system.
- Heart valves are crucial for unidirectional blood flow.
- The heart's position and orientation are important anatomical features.
- The pericardium, a fibrous sac, encloses the heart.
Mediastinum
- The mediastinum is a central structure within the thoracic cavity.
- Structures within the mediastinum include the heart, great vessels, esophagus, etc.
- Boundaries of the different mediastinums should be distinguished.
