Study Notes
Muscle and Epithelial Tissue
- Muscle tissue is responsible for contractions that produce movement in the body.
- Simple squamous epithelium is made up of flat, thin cells arranged in a single layer.
- Epithelial secretions can provide enzymes via ducts, while ductless secretions function as hormones.
Organ Structure and Types of Epithelium
- Organs lined with multiple layers of cells lacking blood vessels likely have epithelial tissue.
- The most delicate form of epithelium is simple squamous epithelium, known for its thin structure.
- Keratinized epithelium covers the skin, providing a protective barrier.
- Mesothelium refers to epithelium that lines body cavities.
Types of Epithelium and Glandular Functions
- Transitional epithelium, found in the urinary bladder and related organs, accommodates stretching.
- Ducts of sweat and mammary glands are lined with stratified cuboidal epithelium.
- Apocrine secretion involves the release of cytoplasm along with the product.
- Endocrine glands release products into interstitial fluid and are termed ductless, while exocrine glands utilize ducts for secretion.
Connective Tissue Overview
- The three types of connective tissue are:
- Connective tissue proper
- Fluid connective tissue
- Supporting connective tissue
- Connective tissues contain three protein fibers: reticular, collagen, and elastic fibers.
- Plasma cells in connective tissue produce antibodies.
Blood and Its Components
- Dense irregular connective tissue offers strength and support against multidirectional stress.
- Red blood cells comprise almost half of blood's volume, while plasma serves as its liquid component.
- Formed elements in blood include red blood cells, white blood cells, and platelets.
- Extracellular fluid is categorized into plasma, interstitial fluid, and lymph.
- Defense cells in blood are referred to as white blood cells.
Cartilage and Bone
- Interstitial growth refers to cartilage development through matrix accumulation around chondrocytes.
- A herniated disc indicates injury to fibrocartilage, which cushions vertebral discs.
- Chondroitin sulfate is prevalent in cartilage's matrix.
- Chondrocytes are the cellular counterparts of cartilage, whereas osteocytes correspond to bone tissue.
- Bone is classified as osseous tissue, a type of supporting connective tissue.
Membranes and Tissue Composition
- Epithelial and connective tissues work together to form body membranes for protection and coverage.
- Mucous membranes line cavities that connect to the body's exterior.
- Serous membranes function to reduce friction between the parietal and visceral surfaces of internal cavities.
