The bones in the skull have many different names but what are the boundaries of each bone? Where do they start and stop? | Bones of the skull are separated by immobile joints called sutures. |
Which of the following can be considered a function of the paranasal sinuses? | Sinuses take away a minimal amount of strength from bones while reducing the weight of bones. |
Which of the bones of the skull would you most associate with hearing and balance? | the temporal bone |
Which of the following would be most associated with housing the special sense organs? | the facial bones |
Which of the following would be most associated with process of warming and humidifying inhaled air? | the paranasal sinuses |
Which is the best description for the function of the cranial bones? | protection of the brain |
The sphenoid bone is sometimes referred to as a "key stone" of the skull. This is due to the fact that ________. | the sphenoid is in the center of the skull and it articulates (joins) with all of the other bones of the skull (excluding the mandible) |
The sella turcica is part of the ________ bone and houses the ________ gland. | sphenoid; pituitary |
The hypothalamus is a region of the brain controlling many aspects of the endocrine system. It works closely with the pituitary gland. The hypothalamus is directly superior to the pituitary and is therefore ________. | superior to the sella turcica |
During concussion the brain will move within the cranial cavity.Ironically one of the bone markings that can cause serious damage to the brain is the________. This is ironic because one of the functions of this bone marking is to ________. | crista galli; attach to the dura matter holding the brain in place |
Curvatures of the spine serve the body by ________. | giving additional springiness and flexibility to the spine which absorbs shock |
When looking at the range of motion of the various sections of the vertebral column the ________ has the most flexibility | cervical spine |
The range of motion as well as the direction of motion for the various regions of the spine differs. While the thoracic spine rotates with little flexion or extension. This is due to variation in ________. | the orientation of the superior and inferior articular facets |
The anatomy of the thoracic cage provides ridged support and protection but at the same time is also flexible and mobile. Of the list below, which feature does not aid in the flexibility and movement of the thoracic cage? | the jugular notch |
The glenohumeral joint that articulates the humerus to the pectoral girdle is a highly mobile joint. This mobility comes at a cost because ________. | the joint is relatively unstable and can easily dislocate |
Of the list below select the one that gives the least explanation for the relatively high mobility of the arms. | The subscapular notch is a passage way for nerves. |
The proximal end of the ulna illustrates the relationship of form and function. The rounded trochlear notch articulates with the hourglass shape of the trochlea. This forms a joint that allows for ________. | the hinge like motion of the forearm |
The proximal end of the radius illustrates the relationship of form and function. The cup-like surface of the radial head articulates with the rounded shape of the capitulum. This forms a joint that allows for ________. | the rotational motion of the forearm |
The axial skeleton includes ________. | the skull, vertebral column, and rib cage |
Which vertebra does not have a body? | atlas |
The suture that connects the two parietal bones together is the ________. | sagittal |
The hyoid bone is unique because it ________. | is the only bone of the body that does not articulate with any other bone |
Along with support, the anterior longitudinal ligament of the vertebral column also acts to ________. | prevent hyperextension of the spine |
Paranasal sinuses are found in which of these facial bones? | maxillae |
Which of the following is an abnormal lateral curvature of the vertebral column often seen in the thoracic region | scoliosis |
Which part of the vertebral column receives the most stress by bearing most of the weight of the body? | the lumbar region |
Which bone acts as a moveable base for the tongue? | hyoid bone |
Thoracic vertebrae differ from the other vertebrae in that they have ________. | costal facets |
What is the major function of the axial skeleton? | provide central support for the body and protect internal organs |
What are the major functions of the intervertebral discs? | to absorb shock and provide flexibility to the spine |
