Objectives

? Understand the structure and function of the musculoskeletal system

? Review common terminology ? ICD-10-CM changes in the

musculoskeletal system ? Study common diseases and disorders of

the musculoskeletal system

Overview

? The musculoskeletal system is actually made up of two separate systems.

? The muscular system is responsible for the movement of the body.

? The skeletal system is responsible for providing support for the body.

3

Muscular System

? The muscular system makes up about 40% of a man's body weight and about 23% of a woman's body weight.

? There are three different types of muscle tissues:

? Skeletal ? Cardiac ? Smooth

Muscular System

? Every muscle has the ability to contract to help the body function.

? The cardiac muscle pumps blood throughout the body.

? Smooth muscles are found in hollow parts of the body:

? Stomach, intestines, blood vessels, and the bladder

5

Muscular System

? Skeletal muscles attach to the skeleton to keep bones in place and provides the pulling power to allow us to move around.

? The majority of the skeletal muscles stretch across joints to link two bones together.

3

Muscular System

? There are approximately 650 skeletal muscles in the body.

? They usually work in groups in response to nerve impulses.

? Muscles can only pull, they cannot push ? By working in groups, they allow the same

body part to move in different directions.

7

Muscular System

? The muscles work in pairs that relax and contract to move a joint.

? Front leg muscles contract when the knee extends (straightens out)

? Back leg muscles relax when the knee extends (straightens out)

Muscular System

? Muscle contractions that move a body part away from the midline of the body are called abduction.

? Muscle contractions that move a body part toward the midline of the of the body are called adduction.

9

Muscular System

? Tendons and ligaments are also part of the muscular system.

? Tendons are fibrous bands that attach muscle to bone.

? Made of special cells called tenocytes, water, and fibrous collagen proteins.

? Creates a permanent bond with the bone that is extremely tough to break.

Muscular System

? Ligaments are fibrous tissue that attach bone to bone.

? They control range of motion of a joint. ? Ensure that the bones move in proper alignment. ? Composed of strands of collagen fibers. ? Arranged in crossing patterns to prevent the joints

from becoming loose, and to maintain stability.

11

Muscles

? Gastrocnemius muscle

? Located in the back of the lower leg ? Runs from the back of the knee to the heel ? Forms the calf muscle along with the soleus

muscle ? Very prone to spasms; painful involuntary

muscle contraction that may last several minutes.

12

6

Muscles

? The primary function of the gastrocnemius muscle is plantar flexion (or movement of the foot).

? Also plays a minor role in flexion of the knee (between the 120 and 150 degree range)

13

Muscles

? Quadriceps

? Large muscle group of four muscles located on the front of the thigh.

? Rectus femoris ? located in the middle of the thigh and covers most of the other three muscles

? Vastus lateralis- located on the outer side of the thigh (lateral)

? Vastus medialis ? located on the inner side of the thigh (medial)

? Vastus intermedius ? located deep within the rectus femoris between the other vastus muscles

14

7

Muscles

? The strongest and leanest muscle in the body. ? The main functions knee extension and hip

flexion.

? It is a weaker hip flexor when the knee is extended because it is already shortened.

? It also becomes less dominant in knee extension when the hip is flexed because it is already shortened.

15

Muscles

? Gluteus maximus

? Largest and most superficial of the three gluteal muscles.

? Gluteus maximus ? Gluteus medius ? Gluteus minimus

? Makes up a large portion of the shape and appearance of the buttocks.
