4 Muscle tissues are contractile, meaning they can shorten and thicken As they contract, they move body parts 3 types: Skeletal Smooth Cardiac Muscle Tissue Characteristics

5 Skeletal Muscle Tissue Usually attaches to bones Controlled by conscious effort (Voluntary) Can be long and narrow Have alternating light and dark cross markings called striations Each cell has many nuclei Move the head, trunk, limbs, and enable us to make facial expressions, write, talk, chew, swallow and breathe

6

7 Skeletal Muscle

8 Smooth Muscle Tissue Lacks striations Cells are shorter, spindle shaped, and have one nucleus Involuntary- cannot usually control by conscious effort In walls of hollow internal organs. (Stomach, intestines, urinary bladder, blood vessels, uterus) EX: move food through the digestive tract

9 *No striations

10 Smooth Muscle

11 Cardiac Muscle Tissue Is only in the heart Striated Branched and form complex networks with single nucleus Involuntary- Can function without nerve impulses Makes up the bulk of the heart, and pumps blood through the heart chambers and into blood vessels

12 Cardiac Muscle

13 Nervous Tissue found in the brain, spinal cord, and peripheral nerves Specialized Neurons Sense changes in the environment and respond by transmitting nerve impulses Coordinate, regulate, and integrate many body functions Neuroglia support and bind the components of nervous tissue
