Study Notes

Connective Tissue

Types: Fibrous (strong and tough, limits movement, prevents bone-to-bone contact), Elastic (supportive, bends easily, found in external ear and epiglottis), and Cartilage (supportive, flexible, found in joints and respiratory tract)
Functions: Support, protection, transportation of materials, storage of energy reserves, and defense of the body

Muscle Tissue

Types: Smooth (involuntary movement, non-striated, found in internal organs), Skeletal (voluntary movement, striated, attaches to skeleton), and Cardiac (involuntary movement, striated, found in heart)
Functions: Movement, balance, and energy storage

Nervous Tissue

Functions: Communication between cells, irritability, and conductivity
Components: Neurons, nerves, and central nervous system (brain, spinal cord)

Tissue Classification

Epithelial (protection, absorption, secretion), Connective (support, protection), Muscle (movement), and Nervous (communication)
Types of Epithelial Tissue: Squamous (flat, irregularly shaped), Cuboidal (cubed shaped), Columnar (columnar with nucleus near bottom)

Epithelial Cells

Squamous: lines heart, blood and lymphatic vessels, body cavities, and alveoli of lungs
Cuboidal: lines kidney tubules and covers ovaries
Columnar: lines ducts, digestive tract, respiratory tract, and glands

Epithelial Glands

Endocrine Glands: produce and secrete hormones directly into bloodstream
Exocrine Glands: produce substances excreted through ducts to outside environment
