100
These allow cells in a tissue to communicate with one another
What are gap junctions?
100
Composed of a strong connective tissue containing collagen and elastic fibers, has great tensile strength, can stretch and recoil easily. This is also where blood vessels, nerves, glands and hair follicles are located.
What is the dermis?
100
Deepest layer of epidermis, contains stem cells undergoing division to produce new keratinocytes
What is stratum basale?
100
A broken bone that protrudes through the skin
What is an open (compound) fracture?
100
Cells that secrete components required to build bones
What are osteoblasts?
200
The three ways that cells can be arranged in layers
What are simple, stratified, and pseudostratifed?
200
Associated with hair follicles, secrete an oily substance that prevents hair from becoming brittle, prevents evaporation of water from the skin's surface, and inhibits the growth of certain bacteria (*name the secretion and the name of the gland that secretes it)
What is sebum (secreted by sebaceous glands)?
200
Contains many layers of flattened, dead keratinocytes that are waiting to be exfoliated with a loofah sponge.
What is stratum corneum?
200
Microscopic bone breaks resulting from the inability to withstand repeated stressful impact
What is a stress fracture?
200
Large cells derived from monocytes and involved in bone resorption?
What are osteoclasts?
300
The four main cell shapes
What are squamous, cuboidal, columnar and transitional?
300
Waxy lubricating substance that impairs the entrance of foreign bodies, insects, bacteria and fungi into external auditory canal (*name the secretion and the name of the gland that secretes it)
What is cerumen (secreted by ceruminous glands)?
300
Langerhans cells (wei qi) are located within this layer, cells are "thornlike"
What is stratum spinosum?
300
A broken bone in which one end of the fractured bone is driven into the other end
What is an impacted fracture?
300
Unspecialized stem cells derived from mesenchyme
What are osteogenic cells?
400
Three main types of cartilage
What are hyaline, fibrocartilage, and elastic cartilage?
400
Found mainly in the skin of the axilla, groin, aerolae, and bearded regions of men and secretes a milky/yellowish sweat that contains lipids and proteins. When this interacts with bacteria it smells like a locker room.
What are apocrine sweat glands?
400
Contains keratinocytes that are undergoing apoptosis (programmed cell death), and lamellar granules that secrete a lipid rich secretion that acts as a water repellent sealant.
What is stratum granulosum?
400
A partial break in a bone in which one side of the bone is broken and the other side bends
What is a greenstick fracture?
400
Mature cells that maintain the daily metabolism of bone
What are osteocytes?
500
Tissue from which all other connective tissues eventually arise
What is mesenchyme?
500
Distributed throughout the skin of most of the body, especially the forehead, palms and soles and secrete a watery/salty secretion that is important for thermoregulation.
What are eccrine sweat glands (aka merocrine sweat glands)?
500
Consists of flattened, clear, dead keratinocytes, present only in thick skin (fingertips, palms, soles).
What is stratum lucidum?
500
A splintered bone, with smaller fragments lying between main fragments
What is a comminuted fracture?
500
Microscopic unit of compact bone tissue
What is an osteon?
