I-multiple choice questions
1) D: gap junctions can be found between cardiac and smooth muscles. They are absent in developed skeletal muscles
2) A: voltage specific sodium channels are selective to sodium ions
3) E: sensory neurons are also known as ascending or afferent neurons which convey the information from the peripheral receptors to Central nervous system
4) A: hypothalamus produces regulatory hormones for anterior pituitary
5) B: stretch reflex, hamstring relaxation. Rest all are polysynaptic.
II) match the following
6- D: epsp (excitatory post synaptic potential)
7- A: axoaxionic synapses
8- B: ipsp(inhibitory post synaptic potential)
9- E: axodendritic synapses
10- B: ipsp
