Integumentary Anatomy
Most superficial layer of the skin
Epidermis (will accept stratum corneum)
Cutaneous sensation of deep pressure
The vertebra is an example of this type of bone
Irregular bone
The function of an osteoprogenitor cell is:
Stem cell derived from mesenchyme, differentiates into osteoblasts
Describe the movement of a synovial joint
Layer of the epidermis that has lamellar granules, contributes to preventing water loss
Stratum granulosum
List the 7 functions of the integumentary system
Thermoregulation, blood reservoir, protection, cutaneous sensation, excretion, absorption, vitamin D synthesis
This term describes the inner latticework of spongy bone
Body support, organ protection, body movement, mineral storage, blood cell production, energy storage
Synarthrosis, amphiarthrosis, and diarthrosis are ____________ classifications of joints.
Functional
Three pigments contributing to skin color
The 4 stages of tissue repair are:
Hemostasis, inflammatory stage, proliferative stage, remodeling stage
Osteoid is an _(in/organic)_ component of bone and contributes to bone ____________.
Organic, flexibility and tensile strength
A hyaline cartilage model is the starting point for this type of bone growth
Endochondral ossification
Give the structural and functional classifications of the hip joint.
Synovial, diarthrosis
Location, type of gland (exo/endo), and mechanism of secretion of apocrine glands
Location: axillary, anogenital, areola regions
Type of gland: exocrine
Mechanism: merocrine
The external environment is extremely hot. What structure in the skin will be activated? How does this structure bring the body back to homeostasis?
Eccrine glands are activated. Eccrine glands produce sweat that gives the body a cooling effect when it evaporates, aiding in thermoregulation.
This type of bone develops from mesenchyme
Flat bones
High blood calcium levels will trigger this hormone to be released. How does this bring blood calcium levels back to homeostasis (2 ways)?
Calcitonin - Puts calcium from the blood back into bones, triggers kidneys to release calcium into the urine
Give the structural and functional classification of the pubic symphysis joint
Cartilaginous, amphiarthrosis
Name all layers/regions of thick skin from superficial to deep
stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum basale, papillary dermis, reticular dermis, hypodermis
What are the ABCDE characteristics of a malignant melanoma?
Asymmetry, border, color, diameter, evolving
Calcification means __________________, while ossification means __________________.
Calcium being built up in a tissue creating a hard barrier; laying down new bone tissue
Why might there be a difference in bone density of the femurs between an olympic weightlifter and someone with a desk job? What cells are involved?
The olympic weightlifter puts added mechanical stress on their femurs, so osteocytes trigger osteoblasts to lay down more bone, resulting in higher bone density.
The person with a desk job has very little additional mechanical stress on their femurs, so osteocytes trigger osteoclasts to resorb bone, resulting in lower bone density.
Give the structural and functional classifications of a gomphosis joint
Fibrous, synarthrosis
