ANSWERS HIGH YIELD A+
◉ integumentary system.
Answer: 10th and final body system. Comprised of skin and all
structures derived from skin such as hair, nails, sweat and oil glands.
Also the largest organ of the body covering a surface area of
approximately 7620 cm^2 (3000 in^2)and 8% of total body mass in
the average adult
◉ functions of integumentary system.
Answer: 1. Regulates body temperature.
2.Protects body, within limits, against microbial invasion and
mechanical, chemical, and ultraviolet (UV) radiation damage
3. Eliminate waste products through perspiration
4. Receive certain stimuli such as temperature, pressure, and pain
5. Synthesize certain vitamins, and bio chemicals such as vitamin D
◉ axial skeleton.
,Answer: Includes all bones that lie on or near the central axis of the
body. Consists of 80 bones and includes the skull, vertebral column,
rubs and sternum
◉ appendicular skeleton.
Answer: The portion of the skeleton that attaches to the axial
skeleton. Consists of all bones of the upper and lower limbs
(extremities) of the shoulder and pelvic girdles. Comprises of 126
bones
◉ sesamoid bones.
Answer: special types of short bones(small, oval shaped) formed
within tendons (most often near joints). Although sesamoid bones
are present even in a developing fetus, they are not counted as part
of the normal axial or appendicular skeleton except for the patellae,
the largest sesamoid bones. The other most common sesamoid
bones are located in the posterior foot at the base of the first toe. In
the upper limb, sesamoid bones are found most commonly in
tendons near the anterior(palmar) surface of the hand at the base of
the thumb. Others may be found in the tendons of other upper or
lower limb joints. May be fractured by trauma; can be demonstrated
radiographically or by CT (computed tomography)
◉ Classification of bones.
Answer: long bones, short bones, flat bones, irregular bones
, ◉ Long bones.
Answer: Consist of a body and and two ends or extremities. Only
found in the appendicular skeleton
◉ compact bone.
Answer: Hard and dense bone tissue. Has a few intercellular empty
spaces that serves to protect and support the entire bone
◉ Body of the bone.
Answer: Contains a thicker layer of compact bone than at the ends,
in order to help resist the stress of the weight placed on them
◉ spongy bone.
Answer: found at the center of short and flat bones and at the ends
of long bones. Highly porous and usually contains red bone marrow,
which is responsible for the production of red blood cells
◉ medullary cavity.
Answer: cavity within the shaft of the long bones filled with fatty
yellow marrow
◉ Periosteum.
Answer: A dense fibrous membrane covers bone except at the
articulating surfaces. Essential for bone growth, repair, and
