REVIEW QUESTIONS WITH VERIFIED ANSWERS | 100%
CORRECT | GRADE A - CHAMBERLAIN
Active transport .....ANSWER.....Movement of molecules across a
cell membrane from a lower concentration to a higher
concentration, requiring energy (ATP).
Passive transport .....ANSWER.....Movement of molecules without
energy from high to low concentration (e.g., diffusion, osmosis,
facilitated diffusion).
Isotonic .....ANSWER.....Equal solute concentration inside and
outside the cell.
Hypertonic .....ANSWER.....Higher solute concentration outside the
cell; water leaves the cell, causing it to shrink (crenation).
,Page 2 of 29
Hypotonic .....ANSWER.....Lower solute concentration outside the
cell; water enters the cell, causing it to swell and possibly burst
(lysis).
Mucous membranes .....ANSWER.....Line cavities open to the
outside (digestive, respiratory tracts).
Serous membranes .....ANSWER.....Line closed cavities (pleura,
pericardium).
Keratinocytes .....ANSWER.....Produce keratin (protection).
Melanocytes .....ANSWER.....Produce melanin (UV protection).
Langerhans cells .....ANSWER.....Immune response.
Merkel cells .....ANSWER.....Sensory function.
Stratum corneum .....ANSWER.....Dead, keratinized cells.
Stratum lucidum .....ANSWER.....Present only in thick skin.
Stratum granulosum .....ANSWER.....Keratinization starts here.
, Page 3 of 29
Stratum spinosum .....ANSWER.....Strength and flexibility.
Stratum basale .....ANSWER.....Mitosis occurs, melanocytes
present.
Papillary layer .....ANSWER.....Contains dermal papillae,
capillaries, and Meissner's corpuscles.
Reticular layer .....ANSWER.....Dense connective tissue, sweat
glands, sebaceous glands, and hair follicles.
First-degree burn .....ANSWER.....Affects only the epidermis
(redness, pain).
Second-degree burn .....ANSWER.....Affects epidermis and part
of the dermis (blisters, severe pain).
Third-degree burn .....ANSWER.....Affects epidermis, dermis, and
underlying tissues (no pain due to nerve damage).
Synarthroses .....ANSWER.....Immovable joints (e.g., sutures).
