1. A. Sensory input

The Central Nervous System which consists of the brain and spinal cord is in charge for consolidating and processing sensory input such as information processing, imagination, memory and communication. It integrates sensory information to compute an appropriate response.

2. C. Integration

Integration is the method of processing stimuli that has been brought into the CNS and determining if a response is necessary. The Central Nervous System is referred to as " central" because it is the body's main communication system. It integrates data--gathers, synthesizes and combines information from the entire body and coordinates activity/ reaction across the whole body.

3. D. All of the above are parts of the CNS

The brain is protected within the skull and consists of the brain stem, cerebrum, cerebellum and diencephalon. The spinal cord is long, tube-like bundle of nervous tissue that relays messages between the brain and the rest of the body. The spinal cord is composed of 31 segments with a pair of spinal nerves for each. Both motor and sensory nerves are situated in the spinal cord.

4. D. All of the above are examples of neuroglia

Astrocytes are star-shaped glial cells that guide the axon, support the synapses and form the blood-brain barrier.

Microglia are located throughout the brain and spinal cord. It is the main form of active immune defense responsible for phagocytosis.

Oligodendrocytes secure the neurons together. It also cushions the axons.

1- The right answer is A) Sensory input: because the CNS receives a sensory message then transmit a motor output.

2- The right answer is C) Integration: it'is the process of combining information from many sources (vision, hearing touch, etc).

3- The right answer is C) sensory nerves: because it is part of peripheral nervous system

Yuri [45]

Answer:

The correct answer will be-

1. Proteins

2. Nervous

3. transmissible spongiform encephalopathies.

4. Mad cow disease

5. Cow

6. Virus

Explanation:

Prions are the infectious particle composed of harmless proteins found in the brain of the animals like humans, cows which are responsible for the degeneration of the nervous tissues of the brain.

These proteins of the prions are resistant to the enzymatic actions and thus they can multiply and accumulate within the neurons and destroys them forming holes in the neurons giving the sponge-like appearance and thus disease is known as transmissible spongiform encephalopathies.

An example of this disease is mad cow disease which spreads from the cow to human by eating the meat of the cow especially brain contaminated with prions which are neither considered viruses nor cells.
