Chapter 4 Flashcards
- secretory organ
- releases secretions into blood, cavity, or surface
Gland
Non-living chemical substances located between connective tissue cells
Extracellular Matrix
Fine network of cells or collagen fibers
Reticular
Outermost layer of embryo
Ectoderm
Cell shaped like a column
Columnar
Scale like, flat shaped cell
Squamous
Epithelium consisting of more than one layer of cells
Stratified epithelium
Firm, smooth, resilient, nonvascular, connective tissue
Cartilage
Mature cell of fibrous connective tissue
Fibrocyte
Produced by and lubricates serous membrane
Serous fluid
- occurring in severe form
- resistant to treatment
- fatal
- invasive and destructive growth
Malignant
Study of neoplasms
Oncology
Ropelike protein of Extracellular matrix
Collagen
Entire cells are shed by the gland and become apart of secretion
(Sebaceous gland)
Holocrine gland
Glossy cartilage tissue consisting of cartilage cells and their matrix
Hyaline cartilage
Consists of a neuron cell body, axon & 2 or more dendrites
Multipolar neuron
Epithelium consisting of single layer of cells
Simple epethilium
Stratified epithelium. Either cuboidal or squamouslike depending on presence or absence of fluid in organ
Transitional epithelium
Thin plate
Lamina
Any swelling or growth
Tumor
Nerve cell body with single axon
pseudounipolar neuron
Unipolar neuron
Substitution of viable cells for damaged or dead cells by regeneration or replacement
Tissue repair
Disk-shaped regions of cell membrane found in stress areas.
- adhesion between cells
- cementing Extracellular material between cells
Desmosome
Embryo giving rise to the brain and spinal cord
Neuroectoderm
Double-layered connective tissue surrounding cartilage
Perichondrium
Spongy bone
Cancellous bone
- Yellow elastic fibrous mucoprotein
- Major connective tissue protein of elastic structures
Elastin
Dense bone with few spaces
Compact bone
Spindle-shaped cells that form connective tissue
Fibroblast
- Central process of neuron
- Conducts action potentials away from the neuron cell body
Axon
Small channel between cells that allows the passage of ions and small molecules between cells
(Intercellular communication)
Gap junction
Specialized Extracellular material located at the base of epithelial cells separating them from underlying connective tissues
Basement membrane
Cells contribute cytoplasm to its secretion
Apocrine gland
cube-like cell shape
Cuboidal
Mucous-producing epithelial cell
Goblet cell
Blood-forming tissue
Hemopoietic tissue
Mature cartilage cell
Chondrocyte
Secretes products with no loss of cellular material
Merocrine gland
Branching of neuron that receives stimuli and conducts potentials toward cell body
Dendrite
Single layers of flattened cells forming an epithelium that lines serous cavities
Mesothelium
Gland that secretes to a surface through a duct
Exocrine gland
Consists of single layer of cells appearing to have multiple layers
Pseudostratified epithelium
half of a desmosome. Attaches epithelial cells to basement membrane
Hemidesmosome
Mature bone cell surrounded by bone matrix
Osteocytes
Middle germ layer of embryo
Mesoderm
Innermost layer of embryo
Endoderm
Holds cells together. Controls what’s gets in and out
Permeability
Tight junctions
Holds cells together, weak glue
Zonula adherens
- Junction between cells in which cell membranes may be fused
- Blocks off space between cells
Zonula Occludens
- consists of numerous polysaccharides attached to protein
- traps large amounts of water
Proteoglycans
Reproduction/reconstruction of injured part
Regeneration
Fibrous tissue replacing normal tissue
Scar
