Question

The strength and hardness of bones is due to the

large number of cells packed together in the bones
many bony calluses within each bone
hard membrane covering the bones
organic materials in the matrix of the bones

Osteoporosis results in weak bones due, in part, to bone reabsorption. A drug would be beneficial for the treatment of osteoporosis if it could

Answer 1

Osteoporosis results in weak bones due, in part, to bone reabsorption. A drug would be beneficial for the treatment of osteoporosis if it could

activate osteoblasts to induce formation of the bone matrix
activate osteoclasts to induce breakdown of the bone matrix
suppress osteoblasts to induce formation of the bone matrix
suppress osteoclasts to induce breakdown of the bone matrix

Answer 2

A break in which of the following would cause a section of bone to die?

Haversian canal, because it provides nutrients for the bone
Haversian canal, because these canals physically support bone cells
Osteoid, because it removes osteoclasts from the bone
Osteoid, because it removes wastes from the bone

Answer 3

You examine a large long bone and notice a canal-like marking that runs parallel with the bone. At the end of the bone and the canal-like marking, there are two large areas with rough surfaces. These markings are most likely a ______________ and two ________________.

suture; crests
fissure; condyles
foramen; tuberosities
sulcus; tuberosities

Answer 9

I. Bone Surface Markings (Divided into depressions and Processes or Projections)
i. Depressions: (Openings allowing blood vessels and nerves to pass)
1. Fissure - narrow, slit-like opening
2. Foramen - round or oval opening through the bone
3. Fossa - shallow and may serve as an articular surface
4. Sulcus/meatus/canal - canal-like passageway
5. Groove - furrow
ii. Processes: (Site of muscle and ligament attachment)
1. Tuberosity - large rounded projection
2. Crest - narrow ridge of bone
3. Trochanter - very large, blunt, irregulary shaped process
4. Line - narrow ridges of bone; less prominent than crest
5. Tubercle - small rounded projection
6. Epicondyle - raised area above a condyle
7. Spine - sharp, slender, often pointed
iii. Processes: (Forms joints)
1. Head - bony expansion carried on a narrow neck
2. Facet - smooth and nearly flat articular surface
3. Condyle - rounded articular projection
4. Ramus – arm-like bar of a bone
