questions with correct answers.
Cerebrum ANS - Part of the brain responsible for conscious though. Highly convoluted and split into
many parts. Has a left and right hemisphere.
Cerebellum ANS - Helps coordinate voluntary movement and balance.
Somatosensory Area ANS - Receives impulses from the sensory receptors of the body.
Visual Area ANS - Receives impulses from the eyes.
Auditory Area ANS - Receives impulses from the ears.
Motor Area ANS - Sends impulses to skeletal muscles to cause the appropriate movement.
Language Area ANS - Include various parts of the cerebrum responsible for communicating by speech,
such as vocabulary memory, lip, tongue and vocal chord control.
Association Area ANS - Close to each sensory area, analyse incoming sensory impulses in the light of
learning and experience.
Corpus Callosum ANS - Nerve bundle linking the two cerebral hemispheres and allowing exchange of
information between them.
Central Nervous System ANS - CNS
CNS ANS - Composed of the brain and the spinal chord.
, Peripheral Nervous System ANS - PNS
PNS ANS - Made up of sensory neurones and motor neurones. Consists of the somatic and autonomic
nervous systems.
Sensory Neurone ANS - Neurones that carry incoming impulses from the sense receptors to the CNS.
Have dendrites in contact with the sense receptors. Short axon.
Motor Neurone ANS - Carry impulses from the CNS to muscles or glands. Long, myelinated axon.
Somatic Nervous System ANS - Deals with functions under conscious control, such as walking and
speaking.
Autonomic Nervous System ANS - Controls functions that happen automatically, such as heart rate.
Parasympathetic ANS - In control at times of rest and relaxation when the heart rate is low and blood
flow is reduced to the muscles and increased to the digestive system.
Sympathetic ANS - In control when the body is active, or excited, and causes heart rate, perspiration
and the redistribution of blood from the digestive system to the muscles.
Antagonistic ANS - The parasympathetic and sympathetic systems are said to be this because of their
opposite effects.
Nerve ANS - Carry impulses from one part of the body to the next.
Neurone ANS - Consist of a nerve cell body and nerve fibres.
Cell Body ANS - Has the nucleus and cytoplasm which contains organelles, including many mitochondria
to generate the large amounts of energy needed.
