1. III. Muscle Tissue · Closely arranged cells
· Little intercellular material
· Proteins in cells enable contraction which allows movement
Proteins are myosin and actin which are arranged in parallel bundles

2. 1.Skeletal muscle 2.Smooth muscle 3.Cardiac muscle
3 Types of Muscle Tissue
1.Skeletal muscle
2.Smooth muscle
3.Cardiac muscle

3. 1. Skeletal Muscle “SVS”
· Attached to bones by a connective tissue called tendons
· Located deep under skin layer
· Controlled by voluntary control
· Cells are striated (alternate light and dark bands)
Production of body movement

4. 2. Smooth Muscle (Visceral) “SIN”
· Walls of blood vessels, stomach, intestines, urinary bladder and uterus.
· Involuntary control
No striations

5. 3. Cardiac Muscle “CIS” · Walls of heart (myocardium)
· Involuntary control
· Striated cells
· Has intercalated discs
(junctions between cells)

6. IV. Nerve Tissue
· Great properties of conductivity and excitability
· Ability to send and carry electrochemical signals fast
· Consists of 2 types of cells
1.Neurons
2.Neuroglia

7. 1. Neurons
· Highly specialized cells that conduct electrochemical signals fast

8. 2. Neuroglia · More numerous in brain and spinal cord
* Maintain and support neurons

9. Questions
Packet p. 63

10. Membranes
Simplest combination of tissue in body to form a unit

11. 4 Types of Membranes 1. Cutaneous · The skin 2. Serous
*Lines thoracic and abdominal cavities
3. Synovial
· Lines inside walls of cavities that surround joints (knee, elbow, shoulder)
4. Mucous
· Lines internal walls of digestive tract and respiratory tract
*Also lines internal organs like ureters, urinary bladder, and urethra (all of urinary tract) and lines all organs of reproductive tract.
