Integumentary system
This type of epidermal cell acts as a touch receptor.
What are Merkel cells
A bone must resist both compression and tension. These inorganic components give bone its hardness and resistance
What are mineral salts/calcium phosphate?
This cervical pair works together to allow rotation of the head.
What are the atlas and axis.
This girdle sacrifices stability for a greater range of upper-limb movement.
What is the pectoral girdle?
What is inversion?
A patient develops a fungal infection that causes the fingernails to become thick and yellow. This nail change is most consistent with this condition.
What is a fungal infection?
A weightlifter develops thicker, stronger bones in areas exposed to repeated stress. This principle explains the change.
What is Wolff's Law?
This region of the axial skeleton contains 7 vertebrae and supports the head.
What is the cervical region?
This forearm bone changes its position relative to the ulna during pronation and supination.
What is the radius?
This functional classification describes a joint that permits slight movement, such as an intervertebral joint.
What is an amphiathrosis?
What are collagen fibers and elastic fibers.
This epiphyseal zone is where older chondrocytes enlarge as they approach the diaphysis.
What is the hypertrophic zone?
A blow to the chest causes this small sternal projection to move toward the heart or liver.
What is the xiphoid process?
A fracture occurs at the most commonly fractured region of the upper arm.
What is the surgical neck of the humerus?
A synovial joint contains this fluid filled space that separates the articulating bones.
What is the joint cavity?
A patient develops a skin tumor after years of UV exposure. The tumor involves keratinocytes from an epidermal layer located above the deepest layer and has the potential to spread to other tissues.
What is squamous cell carcinoma of the stratum spinosum.
This fracture-repair stage converts the soft callus into a firm mass of spongy bone.
What is the bony (hard) callus?
A patient loses sensation after a herniated disc compresses a spinal nerve. This structure normally contains the disc's gelatinous center
What is the nucleus pulposus.
A nerve is compressed after overuse causes inflammation within the wrist causing this condition to happen
What is a carpal tunnel syndrome?
Despite having fewer stabilizing structures, this factor provides the greatest stability to most synovial joints.
What is muscle tone?
In order to cool the body while in hot environments, this action serves to draw heat away from the internal core towards the more superficial body surfaces.
What is dilation of vessels.
A patient has chronically elevated PTH. This bone cell becomes more active and increases bone reabsorption
What are osteoclasts
A patients disc tears after repeated compression and rotation, allowing its inner material to protrude and compress nearby nerves.
What is a herniated disc?
A patient has pain after repeated stress to the weight bearing bone of the lower leg. This bone is affected as a result
What is the tibia
A lateral blow to an extended knee damages these three structures and is known as the unhappy triad.
