NUTRITION

BRAIN

BRAIN STEM

SKULL

SPINAL CORD

CEREBELLUM

Remember!

The brain controls our nervous system

Brain stem is the continuation of the spinal cord. It controls involuntary actions such as our heartbeat, breathing and sleeping.

The skull protects our brain

Cerebellum is the biggest part of our brain.

This is where we process the information from our senses and where we do our cognitive thinking.

We use the cerebellum to take decissions, to study or to play a game.

The main role of cerebellum is controlling our movements, coordination and balance.

The spinal cord is made up of nerve tissue and runs from our brain down our spine.

The spinal cord is protected by the vertebrae.

It controls our reflex actions.

• WHAT PROTECTS OUR BRAIN?
• WHAT CONTROLS THE COORDINATION AND BALANCE?
• WHAT CONTROLS OUR HEARTBEAT?

Answer these quiestions ON YOUR NOTEBOOK. Put the date and take a photo of it and send it by Class Dojo.

Remember that living organisms are made by cells. Cells form tissues, tissues form organs, organs form systems and systems form bodies.

BRAIN

It interprats the information and sends signals to the rest of the body.

MOTOR NEURONS

They send messages from the brain to our locomotor system.

April 30th, 2020

1. WHAT WOULD HAPPEN IF WE DID NOT HAVE A PERIPHEREAL NERVOUS SYSTEM?
2. DECIDE IF THE FOLLOWING MOVEMENTS ARE VOLUNTARY (V) OR INVOLUNTARY (I):
   • Breathing
   • Playing the guitar
   • Blinking
   • Reading
     

Answer these quiestions ON YOUR NOTEBOOK. Put the date, take a photo of it and send it out by Class Dojo.

SENSORY NEURONS

They collect information from our sense organs (eyes, ears, tongue, skin adn nose)

HOMEWORK

May 4th, 2020

HOMEWORK

Draw ON YOUR NOTEBOOK the following table and fill in it:

LENS

It focuses the light on the retina at the back of the eye.

EYELID

An eyelid is a thin fold of skin that covers and protects the eye.

RETINA

A light sensitive layer that lines the interior of the eye. It is composed of light sensitive cells known as rods and cones.

OPTIC NERVE

It sends the information captured by the nerve receptors in the retina to the brain.

BLIND SPOT

Place where the optic nerve leaves the eye. This area does not respond to light.

IRIS

It controls the amount of light that enters in the eye. It gives the eye its color.

CORNEA

The cornea is the transparent front part of the eye wich allows to enter the light and protects the iris, pupil and the lens.

PUPIL

It's a black hole located in the centre of the iris that allows the light to enter up to the retina.

EYELASH

An eyelash or simply lash is one og the hairs that grows at the edge of the eyelid.

AUDITORY CANAL

A canal placed in the outer ear where the sound enters up to the eardrum.

EARDRUM

Part of the middle ear which vibrates due to the sound.

COCHLEA

Part of the inner ear which becomes the sound's vibrations into a electrical signals.

AUDITORY NERVE

It sends the electrical signal to the brain for processing.

MIDDLE EAR

Part of the ear where is placed a small bones which transmites the waves up to the inner ear.

NERVE RECEPTORS

Chemicals substances enter thorugh the nostrails up to the nerve receptors. They become the chemical signal into a electrical signal which is trnasmited through the olfatory nerve to the brain.

NOSTRAILS

Place where the chemical substances enter up to the verve receptors.

TONGUE

It's the part of the mouth which is covered in taste buds.

TASTE BUDS

They have a receptors cells which detect different tastes (salty, sweet, bitter and sour). These receptors become the chemical signal into a electrical signal to the brain.

2 SENSES IN 1

Chemical substances enter in our mouth and nose at the same time. That's the reason because when we have a cold, food tastes different or bland.

NERVES

They detect sensations such as pression, temperature or texture. Nerves send that information through the perpherial nervous system and the spinal cord.

BLOOD VESSEL

It drives blood from the heart to the organs (like skin) and from the organs to the heart.

DERMIS

Skin protects our whole body and it has several layers. One of them is the dermis, which is the middle layer of the skin that contains bood vessels and nerves.

Joints

May 5th, 2020

1. WHAT ARE THE FUNCTIONS OF THE SKELETON?
2. WHICH BONES PROTECT OUR RESPIRATORY SYSTEM?
3. WHAT IS THE DIFFERENCE BETWEEN LIGAMENT AND TENDON?
4. GIVE ME TWO EXAMPLES OF JOINTS AND TELL ME IF ARE FLEXIBLE, SEMIFLEXIBLE OR FIXED.

PLEASE, DO NOT FORGET TO TAKE A PHOTO OF YOUR HOMEWORK AND PUT NEXT TO IT THE DATE.

SHORT BONES

FLAT BONES

LONG BONES

FIXED JOINTS

(Not movement)

SEMI-FLEXIBLE JOINTS

(Only a small amount of movement)

FLEXIBLE JOINTS

(They are important for the movement)

SKULL JOINTS

SHOULDER JOINT

KNEE JOINT

VERTEBRAE

There are over 600 muscles in the human body. These muscles are controlled by the nervous system which makes the muscles contract and relax. There are three types of muscles:

Skeletal muscles

Smooth

MUSCLES

PLEASE, DO NOT FORGET TO TAKE A PHOTO OF YOUR HOMEWORK AND PUT NEXT TO IT THE DATE.

CARDIAC MUSCLES

The cardiac muscle makes up our heart.

SMOOTH MUSCLES

They are found in organs such as the intestine or the stomach.

SKELETAL MUSCLES

They are joined to the bones by tendons. They work in pairs. For example, when the biceps contract, the triceps relax.

Trapecius

Dorsal muscle

Gluteus

Biceps femoris

Calf muscle

Frontal muscle

Pectoral

Abdominals

Quadriceps

Deltoides

Bíceps
