  1. 5.3 Muscle and Nervous Tissue 2.1 Atoms, Ions, and Molecules Sponge: Set up Cornell Notes on pg. 41 Topic: 5.3 Muscle and Nervous Tissue Essential Question: • Distinguish the difference(s) between neurons and neuroglial cells. • Distinguish the difference(s) between neurons and neuroglial cells.

  3. Muscle Tissue Characteristics: Muscle Tissue Skeletal Smooth Cardiac Nervous Tissue Characteristics: Nervous Tissue Neurons Neuroglia Pg. 41

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

  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. Skeletal Muscle

  7. 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

  8. *No striations

  9. Smooth Muscle

  10. 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

  11. Cardiac Muscle

  12. 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

  13. Neuron
