A&P 1 - Q5 - Integument & Osteon quiz

Epidermal layer directly superficial to the stratum lucidum

Stratum corneum

Part of the dermis containing numerous collagen and elastic fibers

Reticular layer

Body response if temperature rises above normal

Blood circulation to the reticular and papillary dermis increases (promoting heat loss)

Destination of melanin after production by melanocytes

Keratinocytes (transported via melanosomes)

Integumentary cancer beginning in the stratum spinosum or superficial strata keratinocytes

Squamous cell carcinoma

Hormone linked to sunlight, vitamin D, and the integumentary system

Calcitriol

Protein found in nails, hair, and the stratum corneum

Keratin

Injection administered directly deep to the deepest strata of the epidermis

Intradermal injection

Most prominent portion of the papillary dermis?

#3

Which number is pointing to the stratum corneum?

#1

Bone term: a narrow crack or slit in a bone

Fissure

Example of an irregular bone

Vertebrae

Hormone that aids calcium absorption from the digestive system via Vitamin D

Calcitriol

Medical condition NOT caused by wear and tear on articular cartilage

Epiphyseal fracture

Structure surrounding the most superficial portion of a bone

Periosteum

Structure NOT present in the central canals of an osteon

Periosteum

Three main sources of calcium in the body

Digestive system/diet, bones, and blood plasma

Large, multinucleate bone cell that secretes acids and enzymes to dissolve matrix

Osteoclast

Biological process that is NOT a function of the skeletal system

ATP generation

Layer of the periosteum containing osteogenic cells, osteoblasts, and osteoclasts

Cellular layer (inner layer)

Bone possessing a coronoid process

Mandible

Medical condition resulting from wear and tear on articular cartilage at the epiphyses

Osteoarthritis

The name for a 'soft spot' in a newborn's skull

Fontanel

Bone tissue layer lining the medullary cavity and covering spongy bone trabeculae

Endosteum

Bone cells most affected by the activity of PTH and Calcitonin

Osteoclasts

What type of ossification will this bone experience?  

Intramembranous ossification

Structure hidden or not visible in a standard 3D osteon wedge diagram

Perforating canal (Volkmann's canal)

The microscopic bony spaces where osteocytes reside

Lacunae (pointed to by #2)

Bone diagram showing overactive osteoclasts and under-active osteoblasts
