MUSCULOSKELETAL+SYSTEM+5

**Body System Checklist - Muscular System and Skeletal System **

Major functions of muscular system and skeletal system **__Muscular System-__** There are three major functions of the muscular system. **__Skeletal System-__**
 * 1) produce motion
 * 2) provide stabilization
 * 3) generate heat
 * to provide movement
 * protect vital organs like the brain and heart
 * gives the body shape for good posture
 * gives the body support for things like breathing

Describe how the **__structure__** of a skeletal muscle cell provides an advantage on its **__function__**. (shape, striations, multinucleated) The __**shape**__ of a muscle cell is long and skinny. These cells contain **__striations__** which are lines that help the muscle contact and come back as it is being used. Muscle cells are also considered **__multinucleated__** because they contian many nuclei located on the periphery. These nuclei produce protein to build the mucsle. This helps the muscle cell move better and overall helps the movement of the body.  Describe the function and locations of each **__FUN__** type of muscle - skeletal muscle, smooth muscle, and cardiac muscle **__Skeletal Muscle-__** These muscles are attached to the bones and they provide monement to the body parts and maintain position and posture. What are tendons and ligaments? **__Tendons-__** connect the muscle to the bone. **__Ligaments-__** are like tendons but they connect bone to bone to help stabalize joints.
 * __Smooth Muscle-__** The smooth muscle allow for fine control and gradual responses in the body. It is located in the walls of hollow internal structures (blood vessels, the stomach, intestines, and urinary bladder)
 * __Cardiac Muscle-__** This muscle is in the heart and it pumps blood through the body.

Include a body diagram and label the **__main muscles__** in the body (front and back) Include a skeleton and label the **__main bones__** in the body. What is the bone marrow? What are the functions of the bone marrow? Consecutive tissue in the cavities of bones. Produces the 3 kinds of blood cells: red blood cells, white blood cells, and platelets. What is osteoarthritis? What are some causes of osteoarthritis? How is it treated? Osteoarthritis is a serious breakdown of cartilage in the joints. You can get steoarthritis from the joint wear-and-tear, joint overuse or injury, inactivity, excess body weight, or it could be from hereditry. This is treated through various ways: excerise, weight loss, stress relief on joints, pain relief techniques, surgery, medications, and therapy. [|Osteoarthritis]

Find 4 fun/interesting facts the muscular and skeletal systems. You may list the facts as sentences or use them to create trivia questions. There are twenty muscles in each hand. Two hundred muscles are used in each step that you take. There are fifty two bones in our feet, out of the two hundred and six in our entire body. Our bones are as strong as steel, if both are the same weight.

The Pelvis

ü Explain how these systems might be involved, or not involved in the driver’s injury. Cite specific evidence.

It is very possible that the spine was broken or effected by the pole. The man could not move his legs, meaning something is wrong with the connection between the spine and the brain. The man is coughing up blood, so the pole could have hit a lung. Although, he is also peeing blood. This could mean that the pole entered the abdomen area, but ribs were broken and punctured a lung.
