Skeletal System
The patella (knee bone) is found in what part of the skeletal system?
Appendicular Skeleton
TRUE or FALSE: Action and Myosin themselves must shorten in order for a muscle contraction to occur.
FALSE
Skin produces more of this when exposed to UV, as it absorbs UV rays. This also provides pigmentation to skin, eyes, and hair.
Melanin
The Aorta is classified as what type of blood vessel?
Artery
This body system maintains homeostasis by moving oxygen and other nutrients. It is comprised of the heart, blood vessels, and blood.
Cardiovascular System / Circulatory System
This girdle consists of the clavicle (collar bone) and scapula (shoulder blade). It is attached to the humerus (upper arm bone).
Pectoral Girdle
Cardiac muscle is found in this part of the body.
Heart
As cells move up through the epidermis, they become filled with this.
Keratin
Prevents backflow of blood by opening and closing in one direction only.
Valve
The bones of the vertebral column (spine) are found in what part of the skeletal system?
Axial
The patella (knee bone) is an example of what joint type?
Synovial / Freely Moving Joint
This is a type of involuntary muscle found in the walls of organs (such as the esophagus). Cells of this muscle type are spindle shaped.
Smooth Muscle
This layer of skin contains no blood cells.
Epidermis
Where does blood move after leaving the pulmonary arteries (what is it moving toward)?
Lungs
This organ (part of the skeletal system) functions in protecting internal organs, producing blood cells, and storing minerals.
Bone
This type of bone is porous. The main function of this bone type is to add strength without adding mass.
Spongy Bone
Myosin heads bind to this protein, pulling it toward the center of the sarcomere.
Actin
Melanocytes are located in this layer of skin.
Epidermis, specifically the stratum basale
This upper chamber of the heart receives de-oxygenated blood from the superior and inferior vena cava.
Right Atrium
This body system is made of skin, nails, and glands.
Integumentary System
The Sternum (breastbone) is located in this part of the skeltal System.
Axial Skeleton
Thick filaments of muscle fiber, anchored at the M-line in a sarcomere.
Myosin
In which layer of the epidermis do cells form a flat dead layer of skin? This is the outermost layer of the epidermis.
Stratum Corneum
The exchange of oxygen and waste gases (like carbon dioxide) occurs in these tiny blood vessels.
Capillaries
This blood vessel moves oxygenated blood from the lungs to the right atrium.
Pulmonary Vein
