Study Notes

Tissues

Tissues are categorized into four types based on structure and function
The four types are epithelial, connective, muscular, and nervous tissues
Epithelial tissues primarily cover surfaces
Connective tissue provides support and shape to the body
Muscular tissue is comprised of elongated cells called muscle fibers or myocytes
Nervous tissue is made up of neurons, also known as nerve cells

Epithelial Tissues

Major functions include acting as selective barriers and producing secretions on their free surfaces
Types include simple squamous, simple cuboidal, and stratified squamous

Simple Squamous Epithelium

Composed of a single layer of flat cells
Found in mesothelium, which lines body cavities
- Examples include the peritoneum (abdominal organs), pleura (lungs), and pericardium (heart)

Simple Cuboidal Epithelium

Composed of a single layer of cube-shaped cells
Lines kidney tubules

Stratified Squamous Epithelium

Composed of several layers of cells
Found in locations such as skin, mouth, and esophagus

Connective Tissue (CT)

Functions include giving, maintaining, and supporting the shape of the body and its structures
Has three components: cells, fibers, and ground substance
Examples of cells include fibroblasts, macrophages, adipocytes

Connective Tissue Fibers

Collagen fibers are the most abundant protein in the human body, strong, and flexible
Collagen fibers are organized in parallel bundles

Muscular Tissue

Composed of elongated cells known as muscle fibers or myocytes
Types include skeletal, cardiac, and smooth

Skeletal Muscle

Each skeletal muscle is an organ composed of hundreds to thousands of muscle fibers
Muscle fibers are specialized cells specifically for skeletal muscles

Nervous Tissue

Composed of neurons, also known as nerve cells
Found in the brain, spinal cord, and nerves
