Skeletal & Muscular System

Skeletal System

Function:

The skeletal system ….

-Holds the body up (structure and shape)

-Protects internal organs

-Helps the body move

-Stores minerals, Calcium, Phosphorus

-Makes blood cells

PARTS-BONES

-make up the skeletal system

-Made of living cells and protein fibers

- Produce blood cells in the bone marrow

- - 206 bones in adult body

- - 300 bones in infant (later fuse together)

PARTS-CARTILAGE- gives shape

-Connects the bones

-Supports the body

-Softer and more flexible than bone

PARTS-LIGAMENTS

-holds bones together at the joins

-Connects bone to bone

-900 ligaments in human body

PARTS-JOINTS

-place where 2 or more bones connect together

-Allow movement

PARTS-TENDONS

-tough connective tissue that

connects bone to muscle

MUSCULAR SYSTEM

Function

The muscular system…

-helps you move

-helps move blood through the body (arteries/veins/capillaries)

-pumps your blood (heart)

-helps you breathe (lungs)

-moves food through digestive system (stomach, intestines)

TYPES OF MUSCLE

SMOOTH MUSCLE

-tissue in walls of organs, arteries, veins

-In the stomach, lungs, and other soft internal organs

-Involuntary movement (moves by itself)

-Controls the way blood flows through circulatory system

TYPES OF MUSCLE

SKELETAL OR STRAITED MUSCLE:

-attached to legs, arms, back, and torso

-Helps to move bones

-Voluntary movement

TYPES OF MUSCLE

CARDIAC MUSCLE:

- only in the heart

-involuntary movement (moves by itself)

CONNECTION TO OTHER SYSTEMS

-Skeletal and muscular system work together to help you move

-Muscular system works with circulatory system to pump blood through the body

-Muscular system works with digestive system to move food through digestion

-Muscular system works with respiratory system to exchange gases

-Muscular system works with excretory system to eliminate waste

-Nervous system controls skeletal and muscular system
