Study Notes
Skeletal Muscle Tissue
- Skeletal muscle tissue is long, multinucleate, and striated
- It is responsible for voluntary movement, posture, and heat generation
- Attached to bones via tendons
Cardiac Muscle Tissue
- Branched, striated fibers with a single nucleus
- Cells are joined by gap junctions for rapid electrical signal conduction
- Under involuntary control
- Collectively, it forms the myocardium or the heart wall
Smooth Muscle Tissue
- Long, non-striated fibers with a single nucleus
- Cells have a thickened middle
- Joined by gap junctions to coordinate involuntary muscle contractions
- Facilitates peristalsis, constriction of airways, and contractions of the urinary bladder and gallbladder
Nervous Tissue
- Composed of two types of cells: neurons and neuroglia
- Neurons generate electrical signals or nerve impulses and consist of a cell body, dendrites, and an axon
- Neuroglia do not generate electrical impulses and synthesize myelin to increase electrical signal transmission speed
Summary of Tissues
- Tissues are composed of cells and extracellular matrix (ECM)
- Epithelial tissues cover and line the body, capable of secreting or absorbing substances like hormones and nutrients, and providing protection from mechanical injury
- Connective tissues join epithelial tissues to deeper tissues and provide support for the body
- Muscular tissue moves the body and generates heat
- Nervous tissue coordinates and controls the body's response to stimuli
