Bones
100
Which cell in the epidermis produces a pigment to protect the nucelus from UV damage
Melanocytes
100
The type of skin cancers from lease malignant to most.
Basal cell carcinoma, squamous cell carcinoma, melanoma
100
True or False: Transcription occurs in the nucleus and translation occurs in the cytoplasm.
True
100
These 2 layers are found in the dermis.
Papillary (superficial) and reticular (deep)
100
___ are cells that secrete unmineralized bone extracellular matrix called osteoid.
Osteoblast
200
Which layer of the epidermis is only found in thick skin
Stratum lucidum
200
This is used to evaluate burns and to estimate volume of fluid loss.
Rule of Nines
200
This enzyme is essential for transcribing the DNA template strand into a single mRNA strand.
RNA Polymerase
200
The dermis contains blood vessels, lymphatic vessels, epidermal hair follicles, oil/sweat glands and ___.
Nerves
200
____ are mitotically active stem cells in the periosteum and endosteum
Osteogenic/osteoprogenitor cells
300
TRUE or FALSE the stratum basale is the only layer of the epidermis that is vascularized (contains blood vessels/capillaries)
False
300
The bone disorder caused by poorly mineralized bones lacking sufficient hydroxyapatite in adults, and vitamin D deficiency in children.
Osteomalacia/rickets
300
Transcription and translation consists of these three stages.
Initiation, elongation, termination.
300
This region of the dermis sends finger like projections up into the epidermis, contains tactile corpuscles, and friction ridges (thick skin only).
Dermal papillae
300
As soon as a bone breaks, what is the first thing that happens?
A Hematoma forms
400
This layer accounts for 3/4 of epidermal thickness and functions to protect deeper cells from the environment, prevent water loss, protect from abrasion, and acts as a barrier
Stratum corneum
400
A group on diseases in which bone resorption exceeds deposit, and seen most in postmenopausal women.
Osteoporosis
400
DNA replication is the process of making 2 semiconservative, identical copies of DNA. What are the 6 enzymes used to do this?
Helicase, single stranded binding proteins, topoisiomerase, primase, DNA polymerase, ligase.
400
These are located in the reticular layer and sense vibration and pressure.
Lamellar/pacinian corpuscles
400
Where does interstitial growth occur and what are the 5 zones?
Epiphyseal plate; resting, proliferation, hypertrophic, calcification, ossification
500
Which layer of the epidermis consists of a single row of stem cells that are mitotically active?
Stratum Basale.
500
This disease is caused by excessive and haphazard bone deposit and resorption causing bone to grow fast and develop poorly.
Paget's disease
500
Determine the polypeptide chain for the following strand of DNA 3'-TACGGTAGCACT-5'
mRNA - AUG CCA UCG UGA
Anticodon - UAC GGU AGC ACU
peptide chain - Met-Pro-Ser-Stop
500
True or False: Flexure lines are found in the papillary layer, tightly secured to deeper structures, and visible on hands, wrists, fingers, soles, and toes.
False
500
This type of growth is reliant on increased stress from muscle activity or added weight.
Appositional growth
