- 2. •WHICH ARE THEFIVE SENSES? •WHY ARE THEY SO IMPORTANT? •WHERE DOES THE INFORMATION RECEIVED TRAVEL TO? •WHY IS THE BRAIN SO IMPORTANT? •WHICH KINDS/TYPES OF ACTIONS ARE CONTROLLED BY THE BRAIN? SIGHT HEARING SMELL TASTE TOUCH THEY ALLOW US TO INTERACT WITH THE WORLD AROUND US AND DETECT/RECEIVE INFORMATION FROM THE EVIRONMENT THE INFORMATION RECEIVED/DETECTED TRAVELS TO THE BRAIN Because the brain analyses/processes this information and it sends an answer/reaction/response It controls our involuntary actions (you can’t control such as breathing) as well as voluntary actions such as thinking and decision making
- 3. HUMAN BEINGS are livingthings THEY PERFORM THREE VITAL FUNCTIONS INTERACTION REPRODUCTIONNUTRITION SEXUAL (2 organisms: male and female) ASEXUAL (1 organism is required) 5 senses Nervous System Locomotor system Omnivore Carnivore Herbivore
- 4. INTERACTION The locomotor systemgives a specific response to each stimulus …we receive information through our 5 sense organs The brain processes the information from our senses and sends messages to different parts of the body (nervous system) It is a three-step process by which… 1st 3rd 2nd
- 5. THE SENSES: SIGHT eyelid lens cornea iris eyelash retina Opticnervepupil 1st 1. The light enters our eyes through the cornea and pupil 2. The amount of light is controlled by the iris 3. The lens focuses/sends the light to the back of the eye (retina) 4. The optic nerve sends the information to hte brain.
- 6. Outer ear Innerear Middle ear Auditory nerve sends the signals to the brain AURICLE The sound waves enter the Ear canal or auditory canal… …and make the Eardrum vibrates The vibrations reach the Cochlea and turns them into a electrical signal Inside the ear canal you will find earwax THE SENSES: hearing1st
- 7. SENSE ORGANS: SMELLand TASTE The chemicals in the air enter our nose through two holes called NOSTRILS They come into contact with the NERVE RECEPTORS And send the info to the brain through the OLFACTORY NERVE Substances come into contact with our TONGUE The tongue is covered by TASTE BUDS (detect different tates and send the information to the brain) 1st If you feel under the weather, your nose will probably be blocked with snot

- 9. SENSE ORGANS: SMELLAND TASTE sour sweet salty bitter umami
- 10. SENSE ORGANS: TOUCH DERMIS(middle layer of the skin) contains NERVES AND BLOOD VESSELS (detect sensations such as heat or texture and send the information to brain) EPIDERMIS (outer layer) Types of textures: smooth and rough, hard and soft. 1st The skin covers and protect our whole body

- 12. The NERVOUS SYSTEM2nd Oneof these systems is the Nervous System Perform/carry out
- 13. NERVOUS SYSTEM: functions •TheNERVOUS SYSTEM processes/analyses the information from our senses and sends messages from the brain to different parts of the body such as the locomotor system. This allows us to respond to the stimuli from our senses •The NERVOUS SYSTEM controls our internal systems such as the digestive or respiratory system. 2nd
- 14. NERVOUS SYSTEM: CENTRAL NERVOUSSYSTEM BRAIN SPINAL CORD: -Runs from the brain down our spine. -Reflex actions -Protected by the vertebrae CEREBRUM: -biggest part -process info from the senses -cognitive thinking CEREBELLUM control movement and balance BRAIN STEM: involuntary actions SKULL/CRA NIUM protects the brain Is made up of 2nd
- 15. ANALYSE AND ORGANISE SPINALCORD: most important NERVE SPINE/BACKBONE: PROTECTS the Spinal Cord ANALYSE AND ORGANISE: key vocabulary
- 16. NERVOUS SYSTEM: PERIPHERAL NERVOUSSYSTEM is made up of NERVES are made up of TINY CELLS CALLED NEURONS They transfer information through the Nervous System using electrical signals Sensory neurons (carry information from our sense organs to the brain) Motor neurons (send messages from the brain to our locomotor system) 2nd
- 17. PERIPHERAL NERVOUS SYSTEM SENSORYNEURONS (collect info from our senses) MOTOR NEURONS (send messages from our brain to our locomotor system)

- 19. LOCOMOTOR SYSTEM BONES JOINTS MUSCLES They make upour skeleton. Over 200 bones! The place where two bones meet (se encuentran) or they are joined. They allow us to move, hold objects... They can contract and relax. They are controlled by the Nervous System 3RD Our body moves in response to signals from our brain
- 20. The Skeleton: FUNCTIONS Ourskeleton protects the main organs of our bodies. My brain is protected by my skull. My heart and lungs are protected by my rib cage.
- 21. Our skeleton also supportsour bodies and keeps them upright. Without the support of our skeletons our bodies would fall to the floor! The Skeleton: FUNCTIONS
- 22. Our skeleton helpsus to walk, run and move. Our muscles are attached to our bones with tendons. We can move because these tendons pull our bones backwards and forwards. The Skeleton: FUNCTIONS
- 23. The Skeleton: bones LONGBONES Such as femur and humerus. They are in our limbs. SHORT BONES Such as our vertebrae. FLAT BONES Such as the parts of our skull or our scapula.
- 24. The Skeleton SKULL CLAVICLE SCAPULA PELVIS FEMU R PATELLA TIBIA ANDFIBULA SPINERIB CAGE HUMERUS RADIUS AND ULNA STERNUM
- 25. JOINTS SHOULDERS ELBOWS WRISTS ANKLES KNEES HIPS FIXED JOINTS They can’tmove. The parts of the skull. SEMI-FLEXIBLE JOINTS They allow a small amount of movement. Vertebrae in our spine. FLEXIBLE JOINTS They allow us to move. Knees, shoulders, ankles… Bones are connected at the joints by strong elastic tissue called LIGAMENTS.
- 26. OVER 600 MUSCLES! SKELETALMUSCLES: VOLUNTARY These muscles are joined to the bones by TENDONS DELTOID BICEPS TRICEP S GLUTEUS CALF MUSCLES QUADRICEPS ABDOMINALS SIX-PACK PECTORAL TRAPEZIUS DORSAL BICEPS FEMORIS FRONTAL MUSCLE
- 27. OVER 600 MUSCLES! SMOOTHMUSCLES: They are found in organs such as intestines or stomach. INVOLUNTARY muscles. CARDIAC MUSCLE: Make up the heart. INVOLUNTARY muscles.
