Study Notes
Macrophages
- Two types: fixed macrophages and free macrophages.
Stem Cells
- Mesenchymal cells divide in response to injury to aid connective tissue repair.
Skin Cell Structure
- Dead skin cells shed in thin sheets due to desmosomes, which are connections reinforced by intermediate filaments.
Epithelial Connections
- Epithelium connects to underlying connective tissue via a basement membrane.
Serous Membrane
- The peritoneum lines the abdominal cavity.
Glandular Secretion
- Unicellular exocrine glands secrete mucus.
Simple Epithelia Function
- Simple epithelia cover surfaces facing mechanical stress.
Types of Connective Tissue
- Three categories include connective tissue proper, fluid connective tissues, and supporting connective tissues.
Body Cavities and Vessels
- Epithelia lining body cavities and blood vessels are classified as simple squamous.
Tissue Examination
- Tissue with cells connected by junctional complexes and lacking blood vessels is epithelial tissue.
Transitional Epithelium
- Located in the lining of the urinary bladder.
Cartilage Composition
- Hyaline cartilage is found between ribs and sternum, and supporting the trachea.
Bone Characteristics
- Bone is distinguished from cartilage by being highly vascularized.
Absorption Adaptations
- Epithelial cells adapted for absorption have microvilli at their free surface.
Cartilage Structure
- Cartilage is surrounded by a fibrous layer called perichondrium.
Secretion Modifications
- Epithelial cells modified for secretion exhibit polarity.
Osseous Tissue
- Osseous tissue is synonymous with bone.
Collagen Production
- Fibroblasts are connective tissue cells responsible for collagen production.
Cell Junctions
- Gap junctions facilitate the exchange of small molecules between neighboring cells.
Gland Functionality
- Endocrine glands are ductless and release products into interstitial fluid; exocrine glands secrete into ducts or onto surfaces.
Specialization for Secretion
- Secretory cells demonstrate clear polarity.
Serous Membrane Functionality
- Damage to serous membranes can lead to adhesions between abdominopelvic organs.
Antibody Production
- Plasma cells are responsible for antibody production.
Tissue Types
- Loose connective tissue is characterized by a framework of fibers and a fluid ground substance containing adipocytes and mast cells.
Intervertebral Discs
- Fibrous cartilage is found in intervertebral discs.
Inflammation Response
- Tissue swelling from inflammation is triggered by histamine release from mast cells, increasing endothelial permeability.
Epithelial Types
- Simple columnar epithelia line the stomach.
Cartilage and Bone Relation
- Chondrocytes in cartilage are analogous to osteocytes in bone.
Tissue Examination
- Multiple layers of cells lacking blood vessels, with one surface open to an organ's cavity, indicates epithelial tissue.
Neural Tissue
- Tissue specialized for the conduction of electrical impulses is neural tissue.
Membrane Types
- Mesothelium refers to body cavities, while endothelium pertains to the heart and blood vessels.
Neuroepithelia Functions
- Epithelial types specialized for sensory functions include neuroepithelia.
Secretions Type
- Duct-based secretions provide enzymes, while ductless secretions function as hormones.
Connection of Muscles and Bones
- Tendons connect skeletal muscles to bones; ligaments connect bones to other bones.
