Muscle and Nerve Tissue

Muscle and Nervous Muscle Tissues: Capable of contracting or shortening Moves body parts Produce heat

Muscles Tissue Types 1. Skeletal (striated) 2. Smooth 3. Cardiac

Skeletal (Striated) Muscle Under voluntary control. Thin cells that extend the entire length of muscle; multinucleated. Location: Attached to bones through entire body Function: Body movement, heat production

Smooth Muscle Unstriated, under involuntary control. Cells are longer but tapered at the ends; single nucleated, nucleus located in the middle of cell Location: Walls of organs, blood vessels, eyes, glands, and skin Function: Move products internally

Cardiac Muscle Striated; involuntary control Single cells with intercalated disks – cell to cell attachment points for communication. Location: Heart Function: Blood movement via heart contraction

Nervous Tissue Sensitive to change in surrounding Coordinate, regulate, and integrate body functions. Function: Receive and Transmit Signals. Location: Brains, Spinal Cord
