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.

Answer 16

Question 17

What is mitosis?

Answer 17

Mitosis is the process where body cells divide into 2, making an extra set of chromosomes and DNA instructions. Mitosis is used when healing a wound or growing.

Question 18

What are organelles?

Answer 18

Just like we have organs in out body, cells have organs in their structure known as organelles. Each kind of organelle helps to keep the cell alive and working. The DNA in the nucleus of a cell gives instructions for a cells functions.

Question 19

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

Answer 19

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

Question 20

What are the 5 main types of cells?

Answer 20

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

Question 21

What are nerve cells?

Answer 21

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

Question 22

What are red-blood cells?

Answer 22

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 23

What are epithelial cells?

Answer 23

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 24

What are skeletal muscle cells?

Answer 24

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

Question 25

What are adipose cells?

Answer 25

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

Question 26

What can infect the body?

Answer 26

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

Question 27

What are pathogens?

Answer 27

A pathogen is any organism that causes disease

Question 28

What do viruses cause?

Answer 28

Viruses cause most colds and flu’s

Question 29

What does fungi cause?

Answer 29

Fungi causes many skin disease

Question 30

What do parasites cause?

Parasites cause mild nausea, belly pain, dramatic weight loss, and diarrhea.

Question 31

What are 3 ways that parasites enter your body?

Answer 31

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

Question 32

What is cancer

Answer 32

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

Question 33

What is different about cancer cells?

Answer 33

• 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 34

What is the cell theory?

Answer 34

• The cell is the smallest living unit in all organisms
• All living things are made of cells
• All cells come from other pre-existing cells

Question 35

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

Question 37

How do tumors affects the body?

Answer 37

Tumors place pressure on organs.

Question 38

What are cells doing during the interphase?

Answer 38

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

Question 39

What are cells doing during the Mitosis phase?

Answer 39

Where cells are splitting and dividing.

Question 40

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.
