Study Notes
Muscle Tissue
- Muscle tissue is responsible for movement through contractions.
- There are three types of muscle tissue: skeletal, cardiac, and smooth
- Skeletal muscle tissue is attached to the skeleton and voluntarily controlled.
- Skeletal muscle cells are striated, multinucleate, and long.
Cardiac Muscle Tissue
- Cardiac muscle tissue is found only in the heart.
- Cardiac muscle tissue contracts involuntarily
- Cardiac muscle tissue is responsible for pumping blood throughout the body.
- Cardiac muscle tissue is striated.
- Cardiac muscle cells have one nucleus.
- Cardiac muscle cells are short and branching, with intercalated discs that connect cells for efficient contraction.
Smooth Muscle Tissue
- Smooth muscles are found in walls of hollow organs such as the stomach, uterus, and blood vessels.
- Smooth muscle tissue contracts involuntarily
- Smooth muscle is responsible for peristalsis.
- Smooth muscle cells are spindle-shaped and lack striations.
- Smooth muscle cells have one nucleus.
The Nucleus: Control Center of the Cell
- The nucleus is the cell's control center.
- The nucleus contains DNA, the genetic material.
- The nucleus directs cellular activities.
- The nucleus contains the instructions for building proteins, which are essential for all cellular functions.
- The nucleus plays a vital role in reproduction and cell division.
The Plasma Membrane: The Cell's Boundary
- The plasma membrane encloses the cell's contents and separates them from the surrounding environment.
- The plasma membrane is a selectively permeable barrier.
- The plasma membrane regulates the passage of substances in and out of the cell ensuring the proper balance of nutrients, waste products, and other essential molecules.
The Cytoplasm
- The cytoplasm is the cellular material outside the nucleus and inside the plasma membrane.
- The cytoplasm contains cytosol, inclusions, and organelles.
Epithelial Tissue
- Epithelial tissue covers the body surfaces and lines body cavities.
- Epithelial tissue functions in protection, absorption, filtration, excretion, and secretion.
- Epithelial tissue cells fit closely together to form sheets.
- Epithelial tissue is avascular (lacks blood vessels).
- Epithelial tissue rests on a basement membrane, a thin, non-cellular layer produced by epithelial and connective tissue.
Simple Columnar Epithelium
- Simple columnar epithelial tissue is single-layered and column-shaped.
- Simple columnar epithelial tissue lines the digestive tract.
- Simple columnar epithelial tissue is specialized for secretion and absorption.
Pseudostratified Columnar Epithelium
- Pseudostratified columnar epithelium appears stratified (layered) but is actually a single layer.
- Pseudostratified columnar epithelium lines the respiratory tract.
- Pseudostratified columnar epithelium is generally ciliated and functions in secretion and movement of mucus.
Connective Tissue
- Connective tissue binds body tissues together.
- Connective tissue is composed of cells and a non-living extracellular matrix.
- Connective tissue is highly vascularized (has many blood vessels) except for cartilage.
- The extracellular matrix is composed of fibers and ground substance.
- Types of connective tissues: bone, cartilage, dense connective tissue, loose connective tissue, and blood.
Bone
- Bone is the most rigid connective tissue and is also called osseous tissue.
- Bone protects and supports the body.
- Bone is composed of bone cells (osteocytes), a hard matrix of calcium salts, and large numbers of collagen fibers.
Cartilage
- Cartilage is less hard and more flexible than bone.
- Cartilage cells are called chondrocytes.
- Types of cartilage: hyaline cartilage, fibrocartilage, and elastic cartilage.
Hyaline Cartilage
- Hyaline cartilage is the most widespread type of cartilage.
- Hyaline cartilage is characterized by abundant collagen fibers hidden by a glassy, rubbery matrix.
- Hyaline cartilage is located in the trachea, attaching the ribs to the breastbone, covering the ends of long bones, the entire fetal skeleton prior to birth, and in the epiphyseal (growth) plates in long bones.
Blood
- Blood is a connective tissue with a fluid matrix called blood plasma and contains blood cells.
- Blood is the transport vehicle of the cardiovascular system.
- Blood carries nutrients, wastes, and respiratory gases throughout the body.
