| Question | Answer |
|---|---|
| tissue | group of cells with similar structure and function |
| Epithelial tissue | covering outer surface or linings inner surface |
| Classification based on? | cell type, shape, number of layers |
| simple squamous epthelium | single layer, smooth, thin and flat |
| Stratifed squamous epithelium | many layers of mostly flat cells |
| Transitional Epithelium | single layer cube-shaped |
| simple columnar epithelium | single layer taller then they are wide |
| Cilated epithelium | columnar cells with cilia |
| Glands | cells of organs that secrete something |
| unicellular | one cell |
| multicellular | similar or dissimilar cells that combine secretions |
| connective tissue | blood, areolar, adipose, fibrous, elastic, bone, cartilage |
| areolar | also called loose |
| Adipose | cells: adipocytes store fat |
| Fibrous | cells: fibroblasts |
| ELastic cells? | Fiberoblasts |
| elastic matrix? | mostly elastin |
| Bone cells? | Osteocytes |
| Bone matrix? | Calcium salts and collagen |
| Cartilage cells? | Chondrocytes |
| Cartilage matrix? | protien |
| Skeletal cells? | Cylindrical |
| Smooth cells? | Tapered ends, single nuclei |
| Cardiac cells? | Branched, one nucleus |
| Neurons | Generate and carry electrochemical impulses |
| Electrochemical impulses | Electrocial impulses travel along the cell membrane |
| Membranes | Epithelial (serous and mucous) and connective tissue membranes |
| Serous membranes | Simple squamous epithelium that line closed body cavities and cover organs in these cavities |
| pleural membrane | lines thoracic cavity |
| serous fluid | covers lungs |
| pericarduim | lines the fibrous pericardium |
| Visceral pericardium | covers the heart |
| peritoneum | lines abdominal cavity |
| mesentary | covers abdominal organs |
| Mucous membranes | line body tracts that have openings to the outside |
| Connective tissue membranes | made of connective tissue |
| Superficial fascia | between skin and muscles |
| periosteum | covers bone, anchors tendons and ligaments to bone |
| perichondrium | covers cartilage |
| synovial | lines synovial joint cavities, secretes synovial fluid |
| deep fascia | covers skeletal muscles, anchors tendons to muscle |
| meninges | covers the brain and spinal cord |
| fibrous pericardium | forms a sac around the heart, lined by parietal pericardium |
