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
Compact bone (characteristics)
Dense and solid, resists compression in one direction. Consists of osteons.
types of tissues of the body
epithelia, connective tissues, muscle tissues, neural tissues
types of epithelia tissue cells
squamous, cuboidal, columnar, transitional
types of connecting tissues
connective tissue proper, blood and lymph, supporting connective tissue
types of dense connective tissue proper
tendons, aponeruosis, ligaments, elastic
tissues that connect bone to bone
ligaments
tissues that stabilzes the vertabrae
elastic
responsible for thetransport of oxygen(and, to a lesser degree,of carbon dioxide) inthe blood
erythrocyte
help defend thebody from infection and disease
leukocyte
cell fragmentsthat function in the clottingresponse that sealsleaks in diamaged orbroken blood vessels
platelet
Provides stiff but somewhat flexible support; reducesfriction between bony surfaces
Hyaline Cartilage
Provides support, but tolerates distortion without damage and returns to original shape
Elastic Cartilage
Resists compression; prevents bone-to-bonecontact; limits relative movement
Fibrous Cartilage
“Little beams”
trabeculae
detect touch, pressure, pain, and temperature
Sensory receptors
