	epiphyses
	periosteum
	medullary cavity
	tendon

In embryos, the skeleton is primarily made of _______, but in the adult, most of the skeleton is _______.

	hyaline cartilage; bone
	elastic cartilage; bone
	bone; hyaline cartilage
	fibrocartilage; bone
	dense regular connective tissue; hyaline cartilage

Name the canals that, in dense bone, are the communication from the outside of the bone to its interior central canals.

	Haversian canals.
	Volkmann's (perforating) canals.
	Central canals.
	Canaliculi.
	Concentric canals.

Single vertebrae are separated by _______, which cushion the vertebrae and absorb shocks.

	intervertebral discs
	bony pad
	ligaments

The _______ bones form the lateral portion of the eye orbits, are lateral to the nose, and articulate with the maxillae.

	zygomatic bones
	palatine bones
	maxillae
	lacrimal bones
	inferior conchae

Which of the following statements regarding bone formation, growth, and remodeling is/are false?

	Bones are remodeled continually in response to changes in blood calcium levels and the pull of gravity and muscles on the skeleton.
	When blood calcium levels drop below homeostatic levels, the parathyroid glands release PTH, a hormone which activates osteoblasts in bones.
	The process by which bones increase in diameter is called appositional growth, a process of long-bone growth that is controlled by growth hormone and, during puberty, by the sex hormones.
	Except for flat bones that form on fibrous membranes, most bones develop using hyaline cartilage structures as their "models."

The ___ bone is inferior to the mandible, superior to the larynx and does not articulate directly with any other bone.

	maxillary bone
	palatine
	hyoid
	vomer
	inferior concha

The coronoid process, olecranon process and trochlear notch are all found on the:

	humerus.
	radius.
	fibula.
	ulna.
	femur.

The coxal bones (ossa coxae) make up the:

	pectoral girdle.
	hip and thigh.
	pelvic girdle.
	vertebral column and sacrum.
	shoulder girdle.

The spinal curvatures in the _______ and _______ regions are referred to as primary curvatures because they are present when we are born.

	cervical; thoracic
	thoracic; sacral
	thoracic; lumbar
	cervical; sacral
	cervical; lumbar

The true ribs:

	refer to the first five pairs of ribs.
