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.
