#	Question	Answer
1	What does the endocrine system provide?	The endocrine system provides chemical integration through hormones.
2	What does the PNS comprise?	The PNS comprises all the nerves of the body associated with the CNS.
3	What is the role of the somatic neural system?	It relays impulses from the CNS to skeletal muscles.
4	What is the function of dendrites?	Dendrites transmit impulses towards the cell body.
5	What are the three types of neurons based on the number of axons and dendrites?	Multipolar, bipolar, and unipolar neurons.
6	What forms the myelin sheath around myelinated nerve fibres?	Schwann cells form the myelin sheath around the axon.
7	What is resting potential?	The electrical potential difference across the resting plasma membrane is called resting potential.
8	What is a synapse?	A synapse is formed by the membranes of a pre-synaptic neuron and a post-synaptic neuron, which may or may not be separated by a synaptic cleft.
9	What separates neurons at a chemical synapse?	A fluid-filled space called the synaptic cleft.
10	What do released neurotransmitters bind to?	They bind to specific receptors on the post-synaptic membrane.
11	What higher mental functions are processed by the brain?	Vision, hearing, speech, memory, intelligence, emotions, and thoughts.
12	What are the components of the forebrain?	The forebrain consists of cerebrum, thalamus, and hypothalamus.
13	Why is the cerebral cortex called grey matter?	It is called grey matter because neuron cell bodies are concentrated there, giving it a greyish appearance.
14	What functions are controlled by the hypothalamus?	It controls body temperature, urge for eating, and drinking.
15	Which canal passes through the midbrain?	The cerebral aqueduct passes through the midbrain.
16	What functions are controlled by the medulla oblongata?	Respiration, cardiovascular reflexes, and gastric secretions.
17	Which neuron structures are asked to be differentiated?	Dendrites and axons.
