CNS consists of...

PNS consists of...

The ANS (autonomic division) of the PNS controls involuntary processes (eg heartbeat, peristalsis, hormone secretion etc). It is divided into two parts :

Neurones generate and transmit electrical impulses called "action potentials". These can be set off by stimuli from:

Myelinated neurones are surrounded by a series of Schwann cells along their length. Between the cell membranes of these cells is a fatty layer called myelin. Other types of neurones do NOT have this myelin sheath. Conduction of electrical signals is significantly slower in:

The transmission of action potentials comes about because of a movement of ions across a nerve cell membrane. The TWO principle ions involved in this are:

The site of transmission of electric nerve impulses between two nerve cells (neurones) or between a neurone and a gland or muscle cell (effector). It's a tiny gap!

Chemical messengers that your body can't function without. Their job is to carry chemical signals (“messages”) from one neurone (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.

There are 50+ neurotransmitter chemicals in the brain and spinal cord. Which of the following is NOT a neurotransmitter?

Very large nerves (like the sciatic nerves in your leg) contain tens of thousands of axons collected together in a "bundle". The bundle has several layers of protective tissue. Which THREE of the following are part of this protective layer?

Sensory receptors (the specialized endings of sensory neurones) respond to different stimuli inside and outside the body. The type which detect pain, touch heat and cold originate in the skin. These are called:

Sensory receptors (the specialized endings of sensory neurones) respond to different stimuli inside and outside the body. The type which detect position of the body in space enabling posture and balance originate in the muscles and joints. These are called:

Nervous tissue is spilt into two types; neurons and neuroglia. Which descriptions match best the neuroglia?

There are three main kind of neuron. Click on the three correct names for these.

Two different kinds of synapse are found. Which is this?

Communicating neurons are very close together

Linked together by gap junctions

Gap junctions contain channels

Direct flow of current one neuron to the next

Two different kinds of synapse are found. Which is this?

No continuity between neurons

No direct flow of current between the neurons

Relies on neurotransmitters (chemical messengers)

Neuroglia (Glial cells) are connective tissue found within the nervous system. These cells do NOT conduct electrical signals, but still have an important role. Which of the following are types of Glial cells?

The most abundant kind of glial cell, with "foot processes" which surround capillaries, making a selective barrier between the brain and blood. They protect the brain from any toxins or chemical changes in the blood.

The smallest and least abundant type of glial cell. Derived from monocytes that migrate from the blood into the nervous system before birth. Dispersed throughout the brain and are phagocytic, removing microbes and damaged tissues at any site of infection or inflammation.

The cells which form the epithelial lining of the ventricles of the brain and central canal of the spinal cord. Secrete CSF (cerebrospinal-spinal fluid) and some have cilia to aid in the flow of CSF.

Found in clusters around nerve cell bodies in grey matter (in the CNS), located close to myelinated nerve fibres. Help to form and maintain myelin in the same way as Schwann cells do in the PNS.

What is the fibrous tissue middle layer of meninges called?

What is the dense outer fibrous tissue layer of meninges which adheres to the inner surface of the skull called?

There are three spaces associated with the layers of the meninges - the epidural, subdural and the subarachnoid spaces. Which one of these contains CSF and is the closer one to the brain?

CSF contains water, salts, glucose, plasma proteins, leucocytes and some creatinine and urea. It has several functions.

Approximately how much CSF (which is secreted at about 0.5ml each minute, but absorbed at the same rate) does a healthy adult have?

All of these are cranial nerves, except one.....

How many sections (and so how many pairs of nerves) are there in the spinal cord?

White and grey matter are found in the brain and spinal cord. Essentially, the grey matter is where the processing is done and the white matter is the channels of communication. So which contains mostly myelinated neurones?
