Study Notes

Carpal and Metatarsal Bones

  • The appendicular skeleton contains eight carpal bones.
  • There are five metatarsal bones in the lower limbs.

Pectoral Girdle

  • The shoulder girdle is also referred to as the pectoral girdle.
  • The pectoral girdle consists of two scapulae.
  • Clavicles originate at the manubrium of the sternum in the pectoral girdle.
  • The shoulder blade is another name for the scapula.

Scapula Anatomy

  • The conoid tubercle and costal tuberosity serve as attachment points for the coracoclavicular ligament.
  • The glenoid cavity is located on the lateral border of the scapula.
  • The anterior, smaller process of the scapula is the coracoid process.
  • The scapula has three borders: superior, medial, and lateral.

Shoulder Joint and Processes

  • The joint formed by the articulation of the glenoid cavity and the humerus is known as the glenohumeral joint.
  • The acromion of the scapula articulates with the lateral end of the clavicle at the acromioclavicular joint.
  • The region of the scapular posterior surface separated by the scapular spine is the supraspinous fossa and infraspinous fossa.

Limb Phalanges and Bone Articulation

  • There are fourteen phalanges found in the upper limbs.
  • The bones that articulate with the clavicles include the scapulae and the sternum.
  • The total number of metacarpal bones in the upper limbs is five.

Function and Movement

  • The major function of the pectoral girdle is to connect the upper limbs to the torso and facilitate movement.
  • The appendicular skeleton allows for movement and manipulation of objects.

Arm Terminology

  • The term "brachium" is another name for the arm.

Proximal Humerus

  • The proximal epiphysis of the humerus features two tubercles: the greater and lesser tubercles.
