Bone functions include: - ANSWER: Muscle attachment, protection and support,
blood cell production, and storage of minerals.
Bones are living tissues that include: - ANSWER: Bone tissue, cartilage, connective
tissue, blood, and nervous tissue
Example of Long Bones: - ANSWER: Femur, humerus
Example of Flat Bones: - ANSWER: Sternum, skull, scapulae
Example of Irregular Bones: - ANSWER: Vertebrae, Coccyx, Sacrum
Example of Short Bones: - ANSWER: Talus, carpals, tarsals
Expanded ends of bones that form joints with adjacent bones are called __________
- ANSWER: Epiphyses
What covers the epiphyses? - ANSWER: Articular (hyaline) cartilage
The shaft of the bone is the _____? - ANSWER: Diaphysis
A though layer of vascular connective tissue called the ________ covers the bone
and is continous with ligaments and tendons. - ANSWER: Periosteum
The diaphysis contains a hollow _______ _______ - ANSWER: Medullary Cavity
The Medullary Cavity in the diaphysis is lined with _______ - ANSWER: Endosteum
The diaphysis contains a hollow medullary cavity that is lined with endosteum and
filled with _______ - ANSWER: Marrow
True or False. Bones are living tissues - ANSWER: True
Where on a bone is the Epiphysis? - ANSWER: The end of the bone
Where on a bone is the Diaphysis? - ANSWER: The main or midsection (shaft) of the
bone
, Where on a bone is the Articular Cartilage? - ANSWER: The Epiphysis
Where on a bone is the Periosteum? - ANSWER: Outer surface, covers around the
bone
Where on a bone is the Medullary Cavity? - ANSWER: In the middle of bone in the
diaphysis of long bones
Where on a bone is the Endosteum - ANSWER: In the middle of bone, lines the
medullary cavity in diaphysis
Compact (Cortical) Bone structure: - ANSWER: Continuous extracellular matrix with
no gaps. Wall of diaphysis. Strength and Support
Spongy (Cancellous) Bone structure: - ANSWER: Branching bony plates called
trabeculae. Interior of epiphysis, surrounded by compact bone, reduces weight of
skeleton.

Osteonic Canals
Bone cells are called _______ - ANSWER: Osteocytes
Bone cells (osteocytes) are located within _________ - ANSWER: Lacunae
________ are small, hollow chambers between layers of lamellae - ANSWER:
Lacunae
Osteonic canals are interconnected by transverse _________ ________. - ANSWER:
Perforating canals
Osteocytes pass nutrients and gases in the matrix through ________. - ANSWER:
Canaliculi
The entire cylinder-shaped unit is called an _______. - ANSWER: Osteon (Haversian
system)
Unlike compact bone, the osteocytes and intercellular material are not arranged
around ________ ________. - ANSWER: Osteonic canals
Bones form by replacing _______ ______ and ________ ________ in the fetus. -
ANSWER: Connective tissue and Hyaline cartilage.
