A&P Lab exam 2 Questions with Detailed
Verified Answers
compact bone Ans: hard, dense bone tissue found immediately deep to the
periosteum.
spongy bone Ans: a network of irregularly-shaped sheets and spikes of bone
(trabeculae). The trabeculae are only a few cell layers thick. The spaces between the
trabeculae contain red or yellow marrow, depending on a person's age and on which
bone it is
osteon Ans: repeating densely packed sub unites.
lamellae Ans: concentric rings of bone matrix. gives the bone compact and a great
deal of strength. (like tree rings)
osteocytes Ans: a bone cell, formed when an osteoblast becomes embedded in the
matrix it has secreted.
periosteum Ans: a dense layer of vascular connective tissue enveloping the bones
except at the surfaces of the joints.
long bone Ans: are longer than they are wide and include the bones of the upper
and lower. (ankle bones, and wrist bones.)
short bone Ans: long as they are wide. the wrist and ankle are short bones

flat bone Ans: they are flat bones including the ribs, sternum, clavicle, certain skull
bones, and pelvic bones.
irregular bone Ans: vertebrae, certain bones of the skull, (lower jaw bone)
diaphysis Ans: the shaft of a long bone
epiphysis Ans: each end of a long bone
epiphyseal plate Ans: band of hyaline cartilage from which long bones grow in
length. when longitudinal growth stops, the chondrocytes of the epiphyseal plate die
and are replaced by calcified bone tissue.
cranial bones Ans: encase the brain
facial bones Ans: Any of the bones surrounding the mouth and nose and
contributing to the eye sockets, including the upper jawbones, the zygomatic, nasal,
lacrimal, and palatine bones, the inferior nasal concha and the vomer, lower jawbone,
and hyoid bone.
suture Ans: cranial bones joined at immovable joints
hyoid bone Ans: a U-shaped bone in the neck that supports the tongue.
vertebrae Ans: each of the series of small bones forming the backbone, having
several projections for articulation and muscle attachment, and a hole through which
the spinal cord passes.
true ribs Ans: ribs 1-7, because they are attached directly to the sternum by their
own cartilage.
