Document Summary
Tissues: groups of cells with similar structure and specialized function. Muscle tissue: specialized for contracting and generating force. There are 3 types of muscle tissue: skeletal muscle (moves the skeleton focus on this course), cardiac muscle (pumps blood out of the heart, smooth muscle (encloses and controls movement of contents through hollow tubes and organs) Nervous tissue: consists of cells specialized for initiating and transmitting electrical impulses. Epithelial tissue: cells that are specialized for exchanging materials between the cell and its environment. Organized into two general types of structures: 1. Gastrointestinal tract) and 2. secretory glands (many kinds). The cells here are very good at controlling what comes in and out of body: exocrine: products released to surface (spit, tears, endocrine: products released to the blood (insulin, hormones) Connective tissue: connects, supports, and anchors various body parts, distinguished by having relatively few cells dispersed within an abundance of extracellular material, examples: tendons, bone, blood.
