= Muscle Space: The Human Machine!!! =

What a muscle //looks// like?

 * Muscles look like the inside of a rubber band or the rubber band as a whole.

**Parts of a Muscle** **Different types of Human Muscles** **Functions of Muscles** **How Muscles interact w/ other parts of the Human body**
 * The muscle is composed of muscular cells. Inside the cells are Myofibrils  and these contain Sacromeres  which, are composed of Actin  and Myosine  proteins. Individual muscle fibers are surrounded by Endomysium , then the muscle fibers are brought together by Paramysium  into bundles, and then these bundles are grouped together forming a muscle.
 * Skeletal - are attached to bones mostly in our legs, arms, chest, neck, face, and abdomen. These bones are made up of fibers, hold the skeleton together, and give the body movement. These muscles also get tired quickly.
 * Smooth - are made up of fibers but are smooth. We can't control these muscles they are controlled by our nervous system. These muscles are found in blood vessels . Also these muscles are harder to contract than any of the other muscles. Smooth muscles do not get tired easily.
 * <span style="color: #ff0000; font-family: Tahoma,Geneva,sans-serif; font-size: 160%; text-decoration: line-through;">Cardiac - Cardiac muscles are found in the heart. These muscles are involuntary muscles. They make it easy to pump blood out the heart into the body for every beat.
 * Muscles pull on our joints which, allows us to move and do other things. Examples would be: <span style="color: #8f0a8f; font-family: 'Comic Sans MS',cursive; font-size: 140%; text-decoration: line-through;">chewing gum, smiling, running, eating, ect.
 * <span style="font-family: Arial,Helvetica,sans-serif; line-height: normal;">Muscles in the muscular system interact with bones of the skeletal system to create movement. Muscles are also used in the esophagus, stomach, intestines and rectum of the digestive system, the respiratory system needs the diaphragm muscle to facilitate breathing, and the heart muscle is serious to the blood pumping of the circulatory system, the urinary system needs the muscles for bladder functions and control.

Wing Discussion

What is the function of a tendon? Tendons connect the muscles to the bone.
 * 1) What function do ligaments perform? Ligaments connect the bones to bones and they help with movement.
 * 1) What is more proximal, the insertion or the origin for the attachment of the muscles in the chicken wing? The organ is more proximal.


 * 1) What tissue is referred to when one speaks of the “meat” of the chicken? Muscle tissue. Muscle tissue


 * 1) Name the two main types of movement that occur when a wing is raised and lowered in flight. Flex and reflex movement.


 * 1) What bone in the wing is connected to the chicken’s body at the shoulder? Humorous.


 * 1) Name the two bones found in the forearm of the wing. The ulna and radius.


 * 1) What type of joint connects the wing to the body? The ball and socket joints in the wing.


 * 1) What type of joint moves the wing at the elbow? Fixed joint that moves in two different directions.


 * 1) The muscle you observed is classified as what type of muscle tissue? Skeletal muscles.
