Slide1

Muscular System

LO- To understand how the muscular system worksName the three bones in your armThe three bones in your arm include…..Describe three functions of skeletal systemE.g- The skeletal system is responsible for BLOOD PRODUCTION. The bone marrow inside larger bones produces blood cells

Slide2

LSQ

The three bones in your arm include the HUMERUS, RADIUS AND ULNAMovement- Skeletal muscles are attached to bones, therefore when the associated muscles contract they cause bones to moveSupport- The skeleton has a framework of the body, it supports the softer tissues.Protection- The skeleton provides protections for many of the body’s internal organsMineral storage- Stores vital minerals such as calcium

Slide3

Muscular System

LO- To understand how the muscular system worksThe Summit- To explain movement using the muscular systemThe Climb- To identify muscles in the muscular system and understand how they work in pairsThe Base- To describe the function of the muscular system

Antagonistic pairs

Contracting

Relaxing

Slide4

Muscles

Muscles are how we move and live.Movement is produced by signals from the brain via the central nervous systemSome muscles work without us thinking, like our heart beating, while other muscles are controlled by our brain.All of our muscles together make up the body's muscular system. There are over 650 muscles in the human body.What muscles can we name?

What are the three types of muscle?

Muscular system 1/02/21

1. Identify three muscles in the leg2. Identify three bones in the body and describe how you remember them3. Describe the characteristics/adaptations of a red blood cell4. Explain how movement is created

Slide8

LSQ answers

1. The three main muscles in the leg are the Quadriceps, Hamstrings and the Gastrocnemius2. Patella (Nutella, chocolate Knee), Clavicle (Collar Bone) Scapula (Shoulder Blade), Humerus (Funny bone), (Elvis) Pelvis, Tibia (

ogether),

ibula (

ar away), Ulna (Underneath), Radius (Circles).3. A Red blood cell has a Large surface area, for oxygen to pass through. It also contains haemoglobin, which joins with oxygen and has no nucleus

4. Movement is produced by signals from the brain via the central nervous system which is then transported to the mucsles

Muscular System

Antagonistic pairs

Contracting

Relaxing

Slide10

Antagonistic muscles

Muscles work in PairsAn example of this is the biceps and triceps in our arms. When the biceps contract the triceps will relax, this allows our arm to bend. When we want to straighten our arm back out, the biceps will relax and the triceps will contract. Muscle pairs allow us to move back and forth.Muscles work together by CONTRACTING and RELAXING When a muscle CONTRACTS it __________, when a muscle RELAXES it ____________

Slide11

Task

An example of an antagonistic muscle pair is the _________ and ____________in our _______. When the _________ contract (__________) the __________will relax(_____________), Biceps

Arms

Lengthens

Shortens

Legs

Quadriceps

Hamstrings

Triceps

Could you think of another pair of antagonistic muscles pair
