Question 1

Body weight is carried primarily by the talus and calcaneus.

The answer of Match the following:
A) Axis
B) Thoracic vertebrae
C) Lumbar...

Question 4

The mastoid sinuses are located at a position in the skull where they are usually free from infections.

Accepted Answer

The mastoid sinuses are actually quite susceptible to infection, and infections in these sinuses can lead to complications such as mastoiditis or meningitis.

B) Connects parietal and frontal bones.
C) Connects temporal and parietal bones.
D) Connects occipital and parietal bones.
E) Connects right and left parietal bones.
-Sagittal suture.

Match the following:
A) Connects occipital and temporal bones.
B) Connects parietal and frontal bones.
C) Connects temporal and parietal bones.
D) Connects occipital and parietal bones.
E) Connects right and left parietal bones.

B) Connects parietal and frontal bones.
C) Connects temporal and parietal bones.
D) Connects occipital and parietal bones.
E) Connects right and left parietal bones.
-Occipitomastoid suture.

Accepted Answer

The occipitomastoid suture connects the occipital bone with the mastoid portion of the temporal bone, hence option E is correct.

Question 8

Match the following:
A) Axis
B) Thoracic vertebrae
C) Lumbar vertebrae
D) Atlas
E) Coccyx
-Allows the head to nod "yes."

Accepted Answer

The atlas (C1 vertebra) supports the skull and allows the head to nod "yes."

Question 9

The vertebral column is held in place primarily by the anterior and posterior longitudinal ligaments.

Accepted Answer

The anterior and posterior longitudinal ligaments are the primary ligaments that run the length of the vertebral column and help to hold it in place. Other ligaments and muscles also play a role in supporting the spine.

Question 10

The frontal bone articulates with the parietal bone by means of the sagittal suture.

Accepted Answer

The frontal bone articulates with the parietal bones by means of the coronal suture, not the sagittal suture. The sagittal suture is the articulation between the two parietal bones.

Question 11

Match the following:
A) Connects occipital and temporal bones.
B) Connects parietal and frontal bones.
C) Connects temporal and parietal bones.
D) Connects occipital and parietal bones.
E) Connects right and left parietal bones.
-Lambdoid suture.

Accepted Answer

The lambdoid suture is the joint between the occipital bone and the two parietal bones.

Question 12

Match the following:
A) Humerus
B) Radius
C) Phalanges
-This bone articulates with the glenoid fossa.

Accepted Answer

The humerus bone articulates with the glenoid fossa of the scapula, forming the shoulder joint. The radius bone articulates with the ulna and the phalanges are the bones of the fingers and toes, which do not articulate with the glenoid fossa.

Question 13

Match the following:
A) Humerus
B) Radius
C) Phalanges
-Forearm bone that articulates with most of the carpals.

Accepted Answer

The radius is the forearm bone that articulates with most of the carpals of the wrist. The humerus is the bone in the upper arm, and the phalanges are the bones in the fingers and toes.

Question 14

The most common site of fracture in the humerus is the anatomical neck.

Accepted Answer

The most common site of fracture in the humerus is the surgical neck, not the anatomical neck.

Question 15

Match the following:
A) Axis
B) Thoracic vertebrae
C) Lumbar vertebrae
D) Atlas
E) Coccyx
-The fused rudimentary tailbone.

Accepted Answer

The fused rudimentary tailbone is known as the coccyx.

Question 16

All of the bones of the skull, except the mandible, are united by sutures and are therefore immovable.

Accepted Answer

Sutures are fibrous joints that connect the bones of the skull and are immovable, therefore making all the bones of the skull, except the mandible, immovable.

Question 17

Match the following:
A) Axis
B) Thoracic vertebrae
C) Lumbar vertebrae
D) Atlas
E) Coccyx
-These bones have articular facets for the ribs.

Accepted Answer

The thoracic vertebrae have articular facets for the ribs to attach to.

Question 18

The fibula is the major weight-bearing bone of the leg.

Accepted Answer

The tibia is the major weight-bearing bone of the leg, while the fibula is a smaller bone that provides lateral support.

Question 19

Match the following:
A) Axis
B) Thoracic vertebrae
C) Lumbar vertebrae
D) Atlas
E) Coccyx
-These bones have the thickest centrum with short blunt spinous processes.

Accepted Answer

The answer of Match the following:
A) Axis
B) Thoracic vertebrae
C) Lumbar...

Question 20

Match the following:
A) Connects occipital and temporal bones.
B) Connects parietal and frontal bones.
C) Connects temporal and parietal bones.
D) Connects occipital and parietal bones.
E) Connects right and left parietal bones.
-Coronal suture.

Accepted Answer

The coronal suture connects the parietal bone to the frontal bone.
