Answer 1

1) Tendon :

a) joins two bones over a ball-and-socket joint is a joint/articulation but not tendon

b) connects muscles to bones is a true statement about tendon that join muscle and bone

c) can be either fast-twitch or slow-twitch type is false statement it is about of muscle

d) is found between fibrous and cartilaginous joints is false statement

2) involuntary muscle :

a. tongue - voluntary muscle
b. thigh - voluntary muscle
c. heart - involuntary muscle - muscle that is not under our control
d. bicep - voluntary muscle

3) The integumentary system includes hair, fingernails, and skin

4) The subcutaneous fat layer of your skin :

a. made up of mostly dead cells, flaking away - false statement
b. is the outermost layer; contains many pores - false statement it is innermost layer
c. cushions large blood vessels and neurons - true statement consists of fats and connective tissues that includes blood vessels and nerves and can act as insulator
d. contains cells that make elastin and collagen - false statement because elastin is not present

5) Pigment that absorbs harmful ultraviolet sunlight : Melanin which is also know as dark pigment that protect skin from damage caused by UV sunlight by absorbing them

6) Sweat glands found in the skin help maintain homeostasis by controlling body temperature. When body gets hot the sensory neurons in the skin get activated and exhaust heat in the form of sweat. when body gets cold the sensory neurons in the skin deactivates and block exhausting heat.

7) The set of characteristics best describes the dermis :

a. contains glands that produce oils or sweat - correct statement
b. produces protective melanin and keratin - incorrect statement it is epidermis
c. insulates the muscles and internal organs - subcutaneous layer
d. consists of layered, tough, waterproof protein - incorrect statement it is epidermis
