| Question | Answer |
|---|---|
| adipose | a type of loose connective tissue that stores fat (energy) in cells called adipocytes, provides insulation and protects organs |
| areolar tissue | a loose connective tissue with a gel-like matrix and a loose arrangement of fibers. It holds organs in place, cushions them, and supports epithelia |
| bone | a connective tissue that provides structural support, protects organs, allows for movement, and stores minerals |
| connective tissue | a diverse group of tissues that support, bind together, and protect other tissues and organs. includes blood, bone, and cartilage. |
| dense connective tissue | tough tissue thats rich in collagen fibers that supports and protects body structures (found in tendons and ligaments) |
| desiccation | processes of becoming dried out with removal of moisture. |
| elastic cartilage | flexible connective tissue containing elastic fibers. provides strength and elasticity to structures like the ear/larynx |
| endocrine glands | glands that release hormones directly into the bloodstream (all secretions are hormones) |
| epithelial tissue | tissue that forms covering on all internal and external surfaces of the body, lines body cavities and hollow organs. is major tissue in glands |
| exocrine glands | glands secret substances like sweat and oil through a duct or opening to body surface or cavity |
| extracellular matrix | non-cellular network of proteins and molecules that surround support and give structure to cells and tissue helps with cell communication and tissue repair |
| fibrocartilage | tough cartilage with a matrix rich in collagen fibers. found in areas that need strong support and resistance to compression, such as intervertebral discs |
| gland | organ or group of cells that make and secret substances like hormones, fluids, and mucus |
| hyaline cartilage | most common type composed of chondrocytes, abundant on collagen fibers, has a rubbery matrix |
| skeletal muscle tissue | attached to the skeleton, this tissue is striated and under voluntary control |
| cardic muscles | in the walls of the heart, striated and involuntary, cells are connected by intercalated discs. |
| smooth muscle tissue | walls of hollow organs like intestines, and stomach, not striated and is involuntary |
| nervous tissue | tissue in the brain, spine, and nerves specialize of generating and transmitting impulses. |
| pseudostratified columnar epithelium | single layer of cells varying heights that gives the illusion of multiple layers . found in respiratory tracts where it secrets mucus and has cilia to move stuff |
| reticular connective tissue | loose connective tissue that form a thin network of reticular fibers. creates the supporting framework for lymphoid organs (spleen) and bone marrow. |
| secretion | process which cell of gland produces and releases a substance |
| hormone | chemical messenger produced be endocrine gland and released into the blood stream to regulate the activity of cells and organs |
| simple columnar epithelium | a single layer of tall cells column shaped specialized for absorption and secretion, lines digestive tract, stomach and intestines. |
| simple cuboidal epithelium | single layer of cube cells that are specialized of secretion and absorption, found in kidney tubules and gland ducts |
| simple squamous epithelium | single layer of flattened cells, allows for easy passage of substances through diffusion, found in the air sacs of the lungs and lining of blood vessels |
| stratified columnar epithelium | tissue of many layers of of column shaped cells that provide protection and secretion, found in urethra and some large gland ducts |
| stratified cuboidal epithelium | rare type of tissue with multiple layers of cube shaped cells that protect areas like ducts of sweat and mammary glands |
| stratified squamous epithelium | multiple layers of flat cells that provide protection against abrasion, forms outer layer of skin, lines mouth and esophagus |
| transitional epithelium | many layers of cells that flatten when stretched, allowing for expansion, lines urinary tract and bladder |
| chondrocytes | special cells found in cartilage tissue that produce and maintain the cartilage matrix |
| lacunae | small cavities within bone and cartilage matrix that store mature cells, like osteocytes and chondrocytes |
| osteocytes | mature bone cells that maintain the bone matrix, located in lacunae |
| collagen | tough fibrous protein that gives support to connective tissues |
| elastin | resilient and elastic protein in connective tissue that allow it to stretch and recoil. |
| reticular fibers | thinnest branching fibers made of type 3 collagen, form supportive framework in soft organs like the spleen and lymph nodes |
| adipocytes | cell that makes adipose tissue, responsible for storing fat (energy) |
| blood plasma | yellowish liquid potion of blood, mostly water, carries blood cells, nutrients, hormones, and waste products |
| intercalated discs | special structures in cardic muscle the connects with nearby cells, allow for easy tansmittion of signals and force for pumping blood with heart |
| striations | the dark and light lines visible in skeletal and cardiac muscle fibers , caused by arrangment of proteins |
| regeneration | process of replacing or restoring damaged or missing cells, tissue, or organs |
| fibrosis | formation of fibrous connective tissue in organ or tissue in reactive process, often result of injury |
