Example Question #2 : Help With Types Of Bone
A rib is an example of a __________ bone.
intrasutural
flat
short
sesamoid
long
flat
Ribs are considered flat bones. Flat bones are generally thin and flat, and can frequently be wide and/or curved. The ribs, sternum, and scapula are considered flat bones.
Long bones are classified as bones with a length that is substantially greater than their width, such as the femur, radius, and phalanges. Short bones, in contrast, have similar length and width measurements, such as the carpals and tarsals. Sesamoid bones are embedded in tendons, such as the patella. Intrasutural bones (or Wormian bones) are found between the primary bones of the skull in abnormal cases of suture formation during development.
Example Question #2 : Help With Types Of Bone
Which of the following is not a long bone?
Axis
Second metatarsal
Fibula
Humerus
Axis
The axis is the only bone listed that is not a long bone. The axis is the second cervical vertebra (C2) and is classified as an irregular bone.
Example Question #1 : Help With Types Of Bone
Which of the following is not a short bone?
Third metacarpal
First cuniform
Hamate
Scaphoid
Third metacarpal
The third metacarpal is the only bone listed that is not a short bone. It is a classifed as a long bone because of its shape and structure, even though it is small.
Example Question #7 : Help With Types Of Bone
Which of the following is a flat bone?
Ulna
Sphenoid
Patella
Scapula
Scapula
The scapula is the only bone listed that is a flat bone. The ulna is a long bone, the sphenoid is an irregular bone, and the patella is a sesamoid bone.
Example Question #81 : Musculoskeletal Physiology
Which of the following is not an irregular bone?
Zygomatic bone
Third cervical vertebra
Frontal bone
Hyoid bone
Frontal bone
The only bone listed that is not an irregular bone is the frontal bone. The frontal bone is a flat bone.
Example Question #3 : Help With Types Of Bone
Which of the following is a sesamoid bone?
Ethmoid
Rib
Talus
Pisiform
Pisiform
The only bone listed that is a sesamoid bone is the pisiform. The ethmoid is an irregular bone, the talus is a short bone, and the rib is a flat bone.
Example Question #2 : Help With Types Of Bone
Which of the following is not considered part of the axial skeleton?
Seventh thoracic vertebra
Pelvis
Sacrum
Mandible
Pelvis
The pelvis is considered to be part of the appendicular skeleton. The sacrum, mandible, and seventh thoracic vertebra are part of the axial skeleton.
Example Question #1141 : Human Anatomy And Physiology
Which of the following is true of compact bone?
Osteoblasts are its most numerous cell population
It is the primary site of hematopoiesis
Its inner surface is lined with the periosteum
It contains Haversian systems, which run longitudinally within the bone
It contains Haversian systems, which run longitudinally within the bone
Compact bone contains Haversian systems, which run longitudinally within the bone.
The primary site of hematopoiesis in adults is the bone marrow, especially that of the pelvis, cranium, vertebrae, and sternum. The periosteum lines the outer surface of the bone; the endosteum lines its inner surface. The most numerous cell type within compact bone is the osteocyte, not the osteoblast.
Example Question #1142 : Human Anatomy And Physiology
Which statement about spongy bone is false?
It is dense and heavy because of the plentiful marrow stored in its cavities
Its processes are arranged at specific angles to withstand common sources of stress
It composes about 20 percent of the body's total bone structure
It is also known as cancellous bone or trabecular bone
It is dense and heavy because of the plentiful marrow stored in its cavities
Spongy bone is made up of a fine lattice of bone tissue, filled with cavities. Even when these cavities is filled with marrow and other tissue, allowing spongy bone to be light in weight compared to compact bone. The other three statements listed are all true.
Example Question #1143 : Human Anatomy And Physiology
In adults, the greatest volume of red blood cells is produced by __________.
long bones
short bones
irregular bones
flat bones
flat bones
The most prolific production sites for red blood cells are the pelvis, cranium, sternum, and vertebrae. Three out of these four sites are flat bones.
