Study Notes
Foot Arches
- The transverse arch is the medial-lateral curvature of the midfoot
- The longitudinal arch is relatively flat
- Hallux valgus is the condition where the great toe points towards the second toe
- Pes cavus occurs when the medial longitudinal arch is abnormally raised
Synovial Joints
- Synovial joints are characterized by articular cartilage, synovial fluid, a joint capsule and ligaments
- Ball-and-socket joints allow free movement in all directions
- The elbow is an example of a hinge joint
- The first two cervical vertebrae (C1 and C2) form a pivot joint
- Synovial fluid acts as lubrication, provides nourishment, and acts as shock absorption
- Ball-and-socket, hinge, pivot, and plane joints are types of synovial joints
- The shoulder is an example of a ball-and-socket joint
- The radius and ulna form a pivot joint
- Abduction is the movement of a body part away from the midline of the body
- The carpal bones in the hand are synovial (typically plane) joints
- Sutures of the skull are examples of an immovable joint
- The joint between the femur and the tibia is a hinge joint
- The pubic symphysis is an example of a cartilaginous joint
- Adduction is the movement of a body part toward the midline of the body
Humerus Structures
- The head, greater and lesser tubercles, deltoid tuberosity, trochlea, capitulum, and epicondyles are structures found on the humerus
- The capitulum is located on the lateral side of the distal end and articulates with the radius
Carpal Bones
- Scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate are the carpal bones
Hand Bones
- Each hand contains five metacarpals
- Each hand contains fourteen phalangeal bones: three in each finger and two in the thumb
Olecranon
- The olecranon is located on the ulna
Carpal Tunnel
- The carpal bones and flexor retinaculum make up the carpal tunnel
Pelvis
- Two coxal (hip) bones make up the pelvic girdle
- The coxal bones articulate with the sacrum
- The pubic symphysis connects the pubic bones anteriorly
- The ilium, ischium, and pubis make up the hip bone
- The ischium is located on the lower and back part of the pelvis
- The three separate hip bones fuse at the acetabulum
Other Bones
- The zygomatic arch is made of the zygomatic bone (cheekbone) and the temporal bone
- Seven bones make up the eye orbit
- The zygomatic bone protects the eyeball from damage in case of trauma
- The sternum is made up of the manubrium (uppermost), body/gladiolus (central), and xiphoid process (small, pointed lower portion)
- Scoliosis is the abnormal curvature of the spine resulting in excessive lateral curvature
- Lordosis is the abnormal curvature of the spine resulting in excessive extension of the lumbar region
Appendicular Skeleton
- Clavicle, scapula, humerus, radius, ulna, carpals, metacarpals, phalanges, coxal (hip) bones, femur, patella, tibia, fibula, tarsals, metatarsals make up the appendicular skeleton
Pectoral Girdle
- The clavicle and scapula make up the pectoral girdle
Scapula Structures
- The glenoid cavity, acromion, coracoid process, and spine are structures found on the scapula
- The acromial end of the clavicle attaches to the acromion of the scapula
Upper Extremity Bones
- The humerus is part of the upper extremity
