Four Major Tissue Type

No TISSUES Date 1>. Four Major Tissue type - Epithelial (Epithelium) 1. Covers and lines body parts 2. Glandular Epithelium 3. Epithelial sheets - . Connective Tissue 1. Special characteristics a. made up of living cells plus non -living extracelluler matrix b. Has nerve supply except cartilage C. Most highly vascular, except cartilage which IS a avascular, and tendons / ligaments which have a low supply. d. Functions - support, protection, binding . - Muscles Tissue 1. generate Force, movement , generate heat 2. three types - skeletal , cardiac , smooth. - Nervous Tissue 1. Initiates and transmits electrical signals 2. Neurons and neuroglia (support cells). Cell junctions 1 Tight junctions 1. adjacent plasma membranes are fused. 2. forms barrier that prevents leakage 3. common in epithelial sheets. - Gap junctions 1. cells linked by protein tunnels called connexons 2. allow small molecules to pass between cells 3. important in conducting electrical signals.

No Date - Desmosomes 1. . scaterred over membrane surface 2. . Found all over body, but more common in tissues that experience stretching. 10. Membranes - . Most are epithelial membrane 1. Epithelium with underlying CT. i. Cutaneous membrane covers body surface i mucous membranes (mucosa) - . Serous membranes (serosa) -. Synoval membranes 1. Line cavaties of synovial joints 2. No Epithelium 3. Areolar CT with elastic fibers and fat 4. Secretes synovial fluid to lubricate joint 26 Lines. 6mm
