Is the scapula in the axial skeleton?
The appendicular skeleton is everything else. It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
How is scapula attached axial skeleton?
The pectoral girdle, which in humans is composed of the scapula (shoulder blade) and clavicle (collar bone), attaches the upper limb to the body. The clavicle connects the upper limb to the sternum (breast bone) by a joint, whereas the scapula is attached to the thoracic cage only by skeletal muscles.
Does the scapula articulate with the axial skeleton?
Because the scapulae do not articulate with the axial skeleton, the shoulder joints are highly flexible, but not very strong. The clavicles and scapulae are extremely important sites for arm muscle attachment and as such provide a sites for arm muscle attachment, and as such provide a base for arm movement.
Which bones are in the axial skeleton?
Your axial skeleton is made up of the 80 bones within the central core of your body. This includes bones in your skull (cranial and facial bones), ears, neck, back (vertebrae, sacrum and tailbone) and ribcage (sternum and ribs).
What is the scapula?
The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.
Is scapula part of the appendicular skeleton?
The appendicular skeleton is divided into six major regions: Shoulder girdle (4 bones) – Left and right clavicle (2) and scapula (2). Arms and forearms (6 bones) – Left and right humerus (2) (arm), ulna (2) and radius (2) (forearm).
What is a scapula?
One of a pair of triangular bones at the back of the shoulder. The scapula connects the collarbone with the upper arm bone. Also called shoulder blade.
What type of bone is the scapula?
flat triangular bone
The scapula is a large, flat triangular bone with three processes called the acromion, spine and coracoid process . It forms the back portion of the shoulder girdle.
Is the scapula part of the appendicular skeleton?
What division of the skeleton is the scapula a part of?
The scapula, along with the clavicle and the manubrium of the sternum, make up the pectoral (shoulder) girdle which connects the upper limb of the appendicular skeleton to the axial skeleton.
What are the 3 main parts of the axial skeleton?
The axial skeleton forms the central axis of the human body and consists of the skull, vertebral column, and thoracic cage.
What are the parts of the scapula?
Scapula
| Borders | Superior, lateral and medial |
|---|---|
| Angles | Lateral, superior and inferior |
| Surfaces | Anterior: subscapular fossa Posterior: supraspinous fossa, spine, infraspinous fossa |
| Processes | Coracoid, acromion |
What bone is the scapula?
The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.
What is the scapula made of?
Some of the outer parts of the scapula are cartilaginous at birth, and would therefore undergo endochondral ossification. At birth, a large part of the scapula is osseous, but the glenoid cavity, the coracoid process, the acromion, the vertebral border and the inferior angle are cartilaginous.
What 4 parts make up the axial skeleton?
The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage.
Where is scapula found?
What are the three main parts of the axial skeleton?
What bones are not part of the axial skeleton?
Which of the following bones is not part of the axial skeleton? D. Sternum.
