Muscle and Nervous Tissue

Muscle Tissue

Characteristics of Muscle Tissue:

• The function of muscle tissue is to contract to produce movement

• There are three types of muscles:

               - Skeletal

               - Smooth
               - Cardiac

   

Skeletal Muscle:

• This type of muscle is attached to the skeleton to provide movement
• They have striations (looks like stripes) 
• Have more that one nucleus
• Shaped like a long cylinder 
• They are the only voluntary type of muscle

Smooth Muscle:

• Found in hollow organs such as stomach, blood vessels, and bronchi
• No visible striations
• Has only one nucleus (uninucleate) 
• Spindle-shaped cells
• Cannot control when or how the muscle moves (involuntary) 

Cardiac Muscle:

• Only found in the heart
• The function is to pump blood throughout the body 
• Also has striations like the skeletal muscle
•  Has only one nucleus (uninucleate)
• Shaped like disks that contains gaps to connect the cells together 

Nervous Tissue

Characteristics of Nervous Tissue:

• The function is to receive and conduct electrochemical impulses to and from body parts
• Makes up the central nervous system(brain) and the peripheral nervous system (nerves throughout the body)
• Nerve cells are called neurons and consist of:

                     - Dendrites: receives the nerve impulse

                     - Cell body: contains the organelles which provide support in transmitting the signal
                     - Axon: transports the response from the cell body
