CT Types

QuestionAnswer
Protein fibers in connective types 1) collagen fibers 2) reticular fibers 3) elastic fibers
Ground substance - made by the primary cell type of the tissue - usually gel-like, but can be hard - cushions, protects, reinforces body structures - holds tissue fluid
Collagen fibers - strongest, resist tension
Reticular fibers - bundles of special type of collagen - cover and support structures
Elastic fibers - contain elastin - recoil after stretching
Loose areolar connective tissue (structure and function) - supports & binds other tissues - holds body fluids - defends against infection (important role in inflammation) - stores nutrients as fat - has all 3 fiber types
Loose areolar connective tissue (location) - widely distributed under epithelia - forms lamina propria of mucous membranes - packages organs - surrounds capillaries
Loose areolar connective tissue (composition) Tissue fluid - water fluid occupies extracellular matrix - tissue fluid derives from blood Ground Substance - viscous, spongy part of extracellular matrix - consists of sugars and proteins - made and secreted by fibroblasts
Loose adipose tissue (structure) - nucleus pushed to one side - richly vascularized - closely packed adipocytes
Loose adipose tissue (function) - provides reserve food fuel - insulates against heat loss - supports and protects organs
Loose adipose tissue (location) - under the skin - around kidneys - behind eyeballs, within abdomen, in breasts - hypodermis
Loose reticular connective tissue (structure and function) - fibers form a strong 3-D network that makes a soft internal skeleton (stroma) with spaces that support matrix and cells - a network of only reticular fibers and loose ground substance
Loose reticular connective tissue (location) - lymph nodes - bone marrow - spleen
Dense irregular connective tissue (structure and function) - primarily irregularly arranged collagen fibers - some elastic fibers - fibroblast is main cell type - able to withstand tension exerted in many directions - provides structural strength
Dense irregular connective tissue (location) - dermis of skin - submucosa of digestive tract - fibrous capsules of joints and organs
Dense regular connective tissue (structure and function) - primarily parallel collagen fibers, some elastic fibers - fibroblasts are common cell type - form fascia - attach muscle to bone, bone to bone - withstand great stress in one direction
Fascia - - layers of fibrous, dense, regular connective tissue that cover and separate muscles and other structures
Dense regular connective tissue (location) - tendons and ligaments - aponeuroses - fascia around muscles
Aponeuroses - sheetlike fibrous membranes that join muscle and the body parts the muscle acts upon
Elastic connective tissue (structure and function) - predominantly elastic fibers - allow recoil after stretching - maintain pulsatile flows of blood in arteries and recoil in lungs after breathing
Elastic connective tissue (location) - within walls of arteries - surrounding bronchial tubes - in certain ligaments
Hyaline cartilage (structure) - imperceptible collagen fibers - amorphous but firm matrix - chondroblasts produce matrix - chondrocytes lie in lacunae
Hyaline cartilage (function) - support and reinforcement - resilient cushion - resists repetitive compressive stress
Hyaline cartilage (location) - embryonic/fetal skeleton - ends of long bones - in joint cavities - costal cartilage of ribs - cartilages of nose, trachea, larynx
Elastic cartilage - more elastic fibers than in hyaline cartilage - maintains shape of structure - allows great flexibility - located in the external ear, epiglottis
Fibrocartilage - matrix less firm than hyaline cartilage - thick collagen fibers predominate - tensile strength and ability to absorb compressive shock - located in intervertebral discs, pubic symphysis, discs of knee joint
Bone - gel-like GS calcified with inorganic salts - matrix contains many collagen fibers - osteoblasts secrete collagen fibers and matrix - osteocytes are mature bone cells: in lacunae
Cutaneous membrane - skin covering outer surface of body - outer epithelium = thick epidermis - inner CT = dense dermis - dry membrane
Mucous membrane - lines hollow organs that open to surface of body - wet and moist membranes - consist of an epithelial sheet underlain with a layer of lamina propria
Serous membrane - simple squamous epithelium lying on areolar CT - produces a slippery fluid - lines closed cavities (pleural, peritoneal, pericardial cavities)
Inflammation (symptoms) - heat - redness - swelling - pain - nearby blood vessels are dilated by histamine
Edema - accumulation of fluid - helps dilute toxins secreted by pathogen - brings oxygen and nutrients from blood - brings antibodies from blood to fight infection
Stages of tissue repair - Regeneration: replacement of destroyed tissue with same type of tissue - Fibrosis: proliferation of scar tissue - Organization: clot is replaced by granulation tissue
