Lab 4 Quiz Flashcards
2 types of neural tissues
Neurons & neuroglia
Cells that are actually transmit the impulse
Neurons
Supporting cells of the neutral tissue; these cells protect the neurons
Neurolgia
Provides padding and cushions shocks; insulates (reduces heat loss); stores energy
adipose tissue
Cushions organs;provides support but permits independent movement; phagocytic cells provide defense against pathogens (Tissue function)
Areolar Tissue
Secrete oily lipid (sebum) that coats hair shaft and epidermis, Provide lubrication andantibacterial action
sebaceous glands
4 cell types in epidermis
keratinocytes, melanocytes, merkel cells, langerhans cells
dermis main parts
papillary layer, reticular layer
formed by stratum germination that extend into dermis. thick skin-friction-fingerprints-improve grip
epidermal ridges
hair follicles (gen anatomy)
internal rooth sheath, external root sheath, glassy membrane, conncetive tissue sheath (fig 4.10)
blood vessels in osteon
Central canal
connect lacunae
Canaliculi
mature bone cells found in lacunae
Osteocytes
osteocytes found here
Lacunae
concentric layers in osteon
Lamellae
