Question 12

What is the Cerebral cortex?

Answer 12

The top 4-mm thick crinkled layer of the cerebrum is called the cerebral cortex. All the brains trickier work- which is called ‘higher processes’ happens in this layer.

Question 13

What is the cerebrum?

Answer 13

The cerebrum is the big bit that we normally think of when we picture ‘the brain’. Its divided into 2 sections, the left and right hemispheres. The left hemisphere controls the right side of the body whereas the right hemisphere controls the left side of the body.

Question 14

What is the cerebellum?

Answer 14

The cerebellum handles muscle control, including balance and movement.

Question 15

What is the brainstem?

Answer 15

The brain stem handles breathing, chewing, your heart rate, coughing, swallowing and more.

Question 16

Note: Each hemisphere is made up of 4 lobes, Within those lobes smaller groups of neurons have their own specific jobs e.g. recognizing faces.

Question 17

What are the 4 different types of tissues in the human body?

Answer 17

• Muscle tissues
• Nervous tissues
• Epithelial tissues
• Connective tissues

Question 18

What are the 5 main types of cells?

Answer 18

• Nerve cells
• Red blood cells
• Epithelial cells
• Skeletal muscle cells
• Adipose cells

Question 19

What are nerve cells?

Answer 19

A type of cell that receives and sends messages from the body to the brain and back to the body.

Question 20

What are red-blood cells?

Answer 20

Red-blood cells are found in your blood. Their main function is to carry oxygen from the lungs and deliver it throughout our body.

Question 21

What are epithelial cells?

Answer 21

Epithelial cells are cells that cover and protect the surfaces of your body. They help keep your body safe, absorb nutrients from food, and make things like sweat.

Question 22

What are skeletal muscle cells?

Answer 22

They’re the muscles that connect to your bones and allow you to perform a wide range of movements and functions.

Question 23

What are adipose cells?

Answer 23

An adipose cell is like a tiny balloon that stores fat.

Question 24

What can infect the body?

Answer 24

Bacteria and viruses, organisms called fungi, and parasites can infect the body.

Question 25

What are pathogens?

Answer 25

A pathogen is any organism that causes disease by feeding on the blood of other cells

Question 26

What are 3 ways that parasites enter your body?

Answer 26

• You may breath in a virus
• Bacteria and parasites enter from food and water
• Others enter through cuts and scratches.

Question 27

What is cancer

Answer 27

Cancer is incontrollable cell growth. These cells are not regulated.

Question 28

What is different about cancer cells?

Answer 28

• May not be able to communicate
• May not be able to carry out all function of a normal cell
• May not be able to follow a specific path of a normal cell

Question 29

What is the cell theory?

Answer 29

• The cell is the basic unit in which the processes of living things take place
• All living things are made of cells and of substances produced by cells
• All cells come from other pre-existing cells

Question 30

Why do cancer cells become this way?

Answer 30

• Genetic
• Exposure to toxins and waste products
• Exposure to radiation
• Exposure to UV light

Question 31

What is a tumor?

Answer 31

A tumor is mass tissue that forms when cells grow and divide more than they should or do not die when they should.

Question 32

How do tumors affects the body?

Answer 32

Tumors place pressure on organs.

Question 33

What are cells doing during the interphase?

Answer 33

• Cells are growing
• Replicating DNA
• Doing their cell functions

Question 34

What are cells doing during the Mitosis phase?

Answer 34

Where cells are splitting and dividing.

Question 35

Note: Depending on what kind of cell it is, it might do mitosis more or less often. For example, hair follicle cells do mitosis frequently which is why your hair grows.

Answer 35

Question 36

What is meiosis?

Answer 36

Meiosis is the cell division of ‘germ cells’ that split in half, then half again creating 4 cells, each with the same number of chromosomes. This occurs during reproduction.

Question 37

What and where is the pupil?

Answer 37

The pupil is the adjustable opening that lets light inside the eye.

Question 38

What is mitosis?

Answer 38

The process by which a single parent cell divides to make two identical daughter cells. This process occurs in primarily prokaryotic cells.
