relates to whether an action and its consequences are right or wrong

consent obtained from a patient where they fully understand the procedure and its implications

a type of cell division that produces genetically identical cells

a cell that can differentiate into specialised cells

Damage and disease in the human brain, including CT and PET scanning

Biology

The human nervous system

Neurones and synapses

The structure and function of a reflex arc

The human eye

Common defects of the human eye

The human brain

Pupils will learn how hormones and glands of the human endocrine system enable us to coordinate and control changes in our bodies.

Pupils learned how substances essential for chemical reactions in living cells, and the products of the reactions, are transported into, around and out of the human body, and the implications of surface area:volume ratio.

This unit explores the structure and function of the nervous system, including the CNS, reflex arcs, and the eye. It covers brain structure, common eye defects, and the challenges in treating nervous system damage. It also addresses ethical considerations.

Coordination and control: the human nervous system

Subjects which particular individuals may be sensitive to, eg, adoption, migration, bereavement or death, divorce, poverty, deprivation.

Depiction or discussion of sensitive content

uses x-rays to scan a patient’s body showing slices of the body

uses a radioactive substance to emit gamma rays that can be detected

Match the type of scan to its description.

When embarking on research into the human brain, what should we consider?

The patient may not be able to consent to the research.

The patient may not benefit from the research.

Patient brain function may be severely limited.

The patient may be harmed from the research.

Which of these statements is **not** an ethical issue involved in studying patients with brain damage caused by Parkinson's?

True or false? Stem cells can cure brain disease.

When the radioactive glucose decays, it emits a positron (a positive electron).

The PET scanner detects glucose used in respiration.

The PET scanner detects gamma rays released from decaying glucose molecules.

The PET scanner detects electrons released from decaying glucose molecules.

The more active a part of the brain is, the more radioactive glucose it absorbs.

Which of the following are true about how a PET (Positron Emission Tomography) scanner works?

Neurones are very complex cells and cannot undergo {{}} to create new copies of themselves.

What type of issues relate to whether an action and its consequences are right or wrong?

What types of cells primarily make up brain tissue?

What is the process of ordinary cell division called?

cells found in the stem of a flowering plant

cells that can differentiate into other types of cell

fMRI imaging uses {{}} radiation to visualise brain activity.

parts of the brain become damaged, affects muscles, e.g. slow movement

associated with an ongoing decline of brain functioning, e.g. memory

involves having a low mood that affects day-to-day living

when the blood supply to part of the brain is cut off
