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 |
