Study Notes
Tissue Types and Functions
- Simple Squamous Epithelium: Facilitates diffusion and filtration; secretes lubricating substances in serosae. Found in kidney glomeruli, air sacs of lungs, and lining of heart, blood, and lymphatic vessels.
- Simple Cuboidal Epithelium: Functions in secretion and absorption. Located in kidney tubules, ovary surface, and ducts of small glands.
- Non-Keratinized Stratified Squamous Epithelium: Protects underlying tissues in areas subjected to abrasion; found in the esophagus, mouth, and vagina.
- Keratinized Stratified Squamous Epithelium: Protects underlying tissues; located in the epidermis of skin.
- Transitional Epithelium: Allows stretching and distension by urine; lines ureters, bladder, and part of the urethra.
- Ciliated Simple Columnar Epithelium: Propels mucus and ovum through ciliary action; found in the fallopian tubes and respiratory tract.
- Ciliated Pseudostratified Columnar Epithelium: Secretes mucus and propels it by ciliary action; present in the trachea and most upper respiratory tract.
Connective Tissue Types
- Loose Areolar Connective Tissue: Wraps and cushions organs, located in the papillary layer of the dermis, around organs, and surrounding blood vessels.
- Adipose Tissue: Insulates against heat loss; supports and protects organs. Found under the skin, around kidneys, and in yellow bone marrow.
- Dense Regular Connective Tissue: Provides strong attachment with forces pulling in one direction, located in tendons, ligaments, and aponeuroses.
- Dense Irregular Connective Tissue: Provides structural strength where tension occurs in many directions; found in the reticular layer of dermis and fibrous capsules of organs.
- Elastic Cartilage: Maintains structure while allowing great flexibility; found in the ear and epiglottis.
- Hyaline Cartilage: Supports and reinforces while resisting compressive stress; located in the embryonic skeleton, articular surfaces of long bones, and trachea.
- Blood: Transports gases, nutrients, and wastes; comprises red blood cells, white blood cells, and platelets.
Muscle Tissue Types
- Skeletal Muscle: Enables voluntary movement; characterized by striations and multinucleated fibers, found in muscles attached to bones.
- Cardiac Muscle: Contracts to propel blood within the circulatory system; marked by intercalated discs and found in the heart.
- Smooth Muscle: Propels substances along internal passageways; found in walls of hollow organs.
Nervous Tissue
- Nervous Tissue: Responsible for transmitting electrical signals; found in the brain, spinal cord, and nerves.
Structures to Identify
- Neuron Cell Body: Includes the nucleus and organelles.
- Chondrocyte in Lacuna: Found in cartilage types such as hyaline and elastic.
- Central Canal: Located in compact bone, housing nerves and blood vessels.
- Goblet Cell: Secretes mucus in non-ciliated simple columnar and ciliated columnar epithelium.
- Elastic Fibers: Present in elastic cartilage and loose areolar connective tissue.
Additional Notes
- Apical View: Observational perspective used to identify the surface layer of epithelium.
- Striations: Characteristic of skeletal and cardiac muscle fibers indicating organized contractile proteins.
- Plasma Membrane and Vacuole: Found in adipose tissue, indicating fat storage.
These notes provide essential insights into various tissue types and their respective functions, locations, and structural characteristics.
