| Question | Answer |
|---|---|
| connective tissue | connective tissue proper, cartilage, bone, blood |
| fibroblasts | secretes matrix |
| matrix | ground substance + fibers |
| ground substance | liquid, semisolid, gel-like or very hard |
| fibers | provide support |
| collagen fibers | white |
| elastic fibers | yellow |
| reticular fibers | fine collagen |
| areolar loose CT fx | wraps & cushions organs, macrophages, inflammation, holds fluid |
| areolar loose CT loc | under epithelium, packages organs, surrounds capillaries |
| adipose loose CT fx | reserve fuel, insulates, protects |
| adipose loose CT loc | under skin, around kidneys & eyeballs, abdomen, breasts |
| reticular loose CT fx | forms stroma, supports immune cell types |
| reticular loose CT loc | lymphoid organs |
| dense regular CT fx | attaches muscles to bones or muscles, withstand strength in one direction |
| dense regular CT loc | tendons, most ligaments, aponeuroses |
| dense irregular CT fx | tension in many directions, strength |
| dense irregular CT loc | fibrous capsules of organs & joints, dermis, submucosa of digestive tract |
| dense elastic CT loc | aorta |
| chondrocytes | produce matrix when mature |
| lacunae | holds chondrocytes |
| hyaline cartilage fx | supports & reinforces cushioning, resists compressive stress |
| hyaline cartilage loc | embryonic skeleton, ends of long bones, costal cartilage, nose, trachea, larynx |
| elastic cartilage fx | maintains structure while maintaining flexibility |
| elastic cartilage loc | external ear (pinna), epiglottis |
| fibrocartilage fx | tensile strength & absorb compressive shock |
| fibrocartilage loc | intervertebral discs, pubic symphysis, discs of knee joint |
| osteocytes | bone cells lie in lacunae |
| integumentary system | protection, insulation, cushioning, waterproofing, regulates heat loss, extretion, synthesis of Vitamin D, sensory organs |
| keratinocytes | most abundant of epidermal cells - make keratin |
| keratin | fibrous protein that gives epidermis its durability and protective capabilities |
| melanocytes | spidery black cells that produce melanin |
| melanin | provides a protective pigment umbrella over the nuclei of keratinocytes to shield from DNA damage |
| laters of epidermis | stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum |
| stratum basale | deepest layer, mitosis |
| stratum spinosum | look spiky |
| stratum granulosum | lamellated granules & keratohyaline granules |
| stratum lucidum | translucent band, only in thick skin |
| stratum corneum | 20-30 cell layers, dead cells |
| dermis | pipillary & reticular regions |
| papillary layer | more superficial, made up of areolar CT |
| dermal papillae | fingerlike projections of papillary layer |
| reticular layer | deepest skin layer, dense irregular CT, contains arteries, veins, sweat & sebaceous glands, Pacinian corpuscles |
| hypodermis | adipose tissue layer under dermis |
| arrector pili | goosebumps |
| sebaceous glands | oil glands, produces sebum |
| sebum | oily substance that lubricates |
| sudoriferous glands | sweat glands, all over body, outlets at pores |
| eccrine glands | all over, produce perspiration (H2O, salts, urea), regulates heat |
| apocrine glands | axillary & genital areas (milky protein & fat plus rich substance) |
| Meissner's Corpuscle | touch receptors in papillary layer |
| Pacinian Corpuscle | deep pressure receptors in reticular layer |
