humerus
The Scapula
Bone cells, osteocytes, reside in cavities within compact bone called lacunae.
No.1 Head of the humerus is fixed in socket of glenoid cavity or scapula thus forming shoulder joint. No.2 Head of femur in acetabulum of hip bone forming hip joint.
I'm assuming it's the clavicle bone which attaches to the sternum on the axial skeleton
This another name for the thoracic cavity. The thoracic cavity contains the heart and lungs.
medulla
The cavity surrounded by the hip bone is called what?
medulla cavity
The shoulder girdle (or pectoral girdle) consists of the clavicle (collar bone) and the scapula (shoulder blade) The Humerus (bone of the upper arm) fits into a cavity in the scapula called the glenoid cavity. The clavicles ("little keys") are long bones that extend across the top of the chest and are attached to the sternum (breast bone) at their medial (towards the midline of the body) ends. The lateral (towards the outside of the body) ends attach to the scapula. The scapulae ("spade" or "shovel") are thin triangular flat bones which lie between ribs 2 and 7.
Temporal bone
The soft tissue inside of the bone is called "marrow."
stem cell
cranial which contains the brain and spinal which contains the nerves of the spinal cord.
