(Axial Skeleton)

b. has the sternal angle located between the manubrium and body
c. receives direct attachments from the costal cartilages of all 12 pairs of ribs
d. articulates directly with the thoracic vertebrae
b. has the sternal angle located between the manubrium and body
(Axial Skeleton)
True ribs are ________.
a. ribs 8–12
b. attached via their costal cartilage to the next higher rib
c. made entirely of bone, and thus do not have a costal cartilage
d. attached via their costal cartilage directly to the sternum
d. attached via their costal cartilage directly to the sternum
Describe a typical vertebra.
A typical vertebra has a vertebral body and a vertebral arch. It has several projections as well as a spinous process and two transverse processes, and as you go down the spine the vertebral body gets bigger.
Describe the structure and function of an intervertebral disc.
The intervertebral disc lies between vertebrae in the vertebral column, and it consists of a nucleus pulposus and an annulus fibrosus. It functions as a cushion between the vertebrae, absorbs shock, and supports body weight.
Describe the parts of the sternum.
The sternum is made up of three parts- the manubrium, the body, and the xiphoid process. The mandible is the wide rectangular portion at the top of the sternum that is above the body, which is the main long, flat part of the sternum. At the very bottom of the sternum is the xiphoid process, which is a tiny, narrow piece of cartilage (which turns to bone around age 40).
(Appendicular Skeleton)
Which part of the clavicle articulates with the manubrium?
a. shaft
b. sternal end
c. acromial end
d. coracoid process
b. sternal end
(Appendicular Skeleton)
A shoulder separation results from injury to the ________.
a. glenohumeral joint
b. costoclavicular joint
c. acromioclavicular joint
d. sternoclavicular joint
c. acromioclavicular joint
(Appendicular Skeleton)
What structure is an extension of the spine of the scapula?
a. acromion
b. coracoid process
c. supraglenoid tubercle
d. glenoid cavity
a. acromion
(Appendicular Skeleton)
Name the short, hook-like bony process of the scapula that projects anteriorly.
a. acromial process
b. clavicle
c. coracoid process
d. glenoid fossa
c. coracoid process
(Appendicular Skeleton)
The radius bone ________.
a. is found on the medial side of the forearm
b. has a head that articulates with the radial notch of the ulna
c. does not articulate with any of the carpal bones
d. has the radial tuberosity located near its distal end
b. has a head that articulates with the radial notch of the ulna
(Appendicular Skeleton)
How many bones fuse in adulthood to form the hip bone?
a. 2
b. 3
c. 4
d. 5
b. 3
(Appendicular Skeleton)
The pelvis ________.
a. has a subpubic angle that is larger in females
b. consists of the two hip bones, but does not include the sacrum or coccyx
c. has an obturator foramen, an opening that is defined in part by the sacrospinous and sacrotuberous ligaments
d. has a space located inferior to the pelvic brim called the greater pelvis
a. has a subpubic angle that is larger in females
(Appendicular Skeleton)
The tibia ________.
a. has an expanded distal end called the lateral malleolus
b. is not a weight-bearing bone
c. is firmly anchored to the fibula by an interosseous membrane
d. can be palpated (felt) under the skin only at its proximal and distal ends
c. is firmly anchored to the fibula by an interosseous membrane
Describe the shape and palpable line formed by the clavicle and scapula.
The clavicle extends laterally across the anterior shoulder and can be palpated along its entire length. At its lateral end, the clavicle articulates with the acromion of the scapula, which forms the bony tip of the shoulder. The acromion is continuous with the spine of the scapula, which can be palpated medially and posteriorly along its length. Together, the clavicle, acromion, and spine of the scapula form a V-shaped line that serves as an important area for muscle attachment.
Your friend runs out of gas and you have to help push his car. Discuss the sequence of bones and joints that convey the forces passing from your hand, through your upper limb and your pectoral girdle, and to your axial skeleton.
(Joints)
The joint between adjacent vertebrae that includes an invertebral disc is classified as which type of joint?
a. diarthrosis
b. multiaxial
c. amphiarthrosis
d. synarthrosis
c. amphiarthrosis
(Joints)
Which of these joints is classified as a synarthrosis?
a. the pubic symphysis
b. the manubriosternal joint
c. an invertebral disc
d. the shoulder joint
b. the manubriosternal joint
(Joints)
Which of these joints is classified as a biaxial diarthrosis?
a. the metacarpophalangeal joint
b. the hip joint
c. the elbow joint
d. the pubic symphysis
