Anatomy Chapter 6
The total number of phalanges in the body is:
56
The wrist bone is an example of:
A short bone
The bones of the spine are examples of:
An irregular bone
Nutrients pass from the blood vessels to the bone cells by way of the:
Canaliculi
Cartilage cells are called:
Chondrocytes
Canaliculi supply food and oxygen to cartilage cells.
False
Going from superior to inferior, the sequence of the vertebrae is cervical, thoracic, lumbar, coccyx and sacrum.
False
Osteoblasts are the bone-resorbing cells.
False
The central canal of the osteon is also called the medullary cavity.
False
The frontal bone of the skull is an example of an irregular bone.
False
The lacuna is a large canal in the center of the osteon that contains a blood vessel.
False
The olecranon process of the humerus and the olecranon fossa of the ulna make up the structure of the elbow.
False
The spine has three curves; two convex and one concave.
False
There are more bones in the axial skeleton than in the appendicular skeleton.
False
The red bone marrow is important in the skeletal function of:
Hematopoiesis
The bone cells in the Haversian system are found in little spaces called:
Lacunae
Trabeculae are:
Needle-like threads of spongy bone
The section of the vertebral column that contains the most vertebrae is the:
Thoracic Section
As long as the epiphyseal plate remains between the diaphysis and epiphysis, bone growth can continue.
True
Both bone and cartilage are examples of connective tissue.
True
Canaliculi are small canals that help supply the bone cells with food and oxygen.
True
Chondrocytes are cartilage cells.
True
Like bone cells, cartilage cells are located in lacunae.
True
Only the true ribs attach to the sternum by the costal cartilage.
True
Osteocytes can be found in the lacunae of the osteon.
True
The "soft spots" in a baby's skull are referred to as fontanels.
True
The concentric rings surrounding the central canal of an osteon are called lamella.
True
The sternum is also called the breastbone.
True
The storage of calcium is an important function of the skeletal system.
True
Ribs that attach individually to the sternum by the costal cartilage are:
True Ribs
Which of the following statements is true of both bone and cartilage?
Both bone and cartilage cells are located in lacunae They both contain more intercellular matrix than cells
A bone can grow as long as this remains:
Epiphyseal plate
As long as this is present in a bone, bone growth can continue.
Epiphyseal plate
Bone-forming cells
Osteoblasts
The bone-resorbing cells are called:
Osteoclasts
Another name for the Haversian system is:
Osteon
Which of the following is not a type of bone?
Round
