Study Notes
Appendicular Skeleton
- The appendicular skeleton makes up 126 bones of the human body.
- The appendicular skeleton allows for movement of the body, including daily tasks and adjustments in posture.
- It includes the pectoral(shoulder) girdle, upper limbs, pelvic girdle, and lower limbs:
Pectoral Girdle
- The pectoral girdle consists of the clavicle and the scapula.
- The clavicle is the collar bone.
- The scapula, or shoulder blade, is a flat, triangular bone.
- The sternoclavicular joint is a synovial joint that provides key movements and stability.
- The acromioclavicular joint is also a synovial joint of the shoulder.
Upper Limb
- The upper limb includes the humerus, radius, ulna, carpals, metacarpals, and phalanges.
- The humerus is the bone in the upper arm.
- The radius is on the thumb side of the forearm
- The ulna is on the pinky side of the forearm.
- The carpals are the bones of the wrist.
- The metacarpals are the bones of the hand.
- The phalanges are the bones of the fingers.
Shoulder Joint
- The glenohumeral joint is a synovial ball & socket joint that allows for a wide range of movements.
- The shoulder joint's joint capsule is weak and reinforced by four muscles called the rotator cuff muscles.
- These muscles are important for stabilizing the shoulder joint.
Wrist Joint
- The joint between the radius and the scaphoid bone allows for flexion, extension, abduction, and adduction of the hand.
Digits
- Joints between the phalanges allow for flexion and extension of the digits (fingers).
- Joints between the metacarpals and the phalanges allow for flexion, extension, abduction, and adduction of the digits.
- The thumb is unique because it has a saddle-shaped joint which allow opposition of the thumb.
Pelvic Girdle
- The pelvic girdle connects the lower limbs to the axial skeleton.
- The pelvis consists of two hip bones.
Lower Limb
- The lower limb includes the femur, patella, tibia, fibula, tarsals, metatarsals, and phalanges.
- The femur is the bone in the thigh.
- The patella is the kneecap.
- The tibia is the larger bone in the lower leg (medial).
- The fibula is slender bone in the lower leg (lateral).
- The tarsals are the bones of the ankle.
- The metatarsals are the bones of the foot.
- The phalanges are the bones of the toes.
Hip Joint
- The hip joint is also a synovial ball & socket joint.
- The hip joint differs from the shoulder joint because it has more reinforcements due to the demands placed on it by the body weight.
Knee
- The knee is a hinge joint, which allows for flexion and extension of the lower leg.
- The anterior cruciate ligament (ACL) is an important ligament in the knee that helps stabilize the joint.
- The most common injury to the knee is an ACL tear.
