a] Give the location of gustatory receptor and olfactory receptor present in human beings. b] Write a and b in the given flow chart of neuron through which information travels as an electrical impulse. "Dendrite"rarrararrb End point of Neuron

Name the parts of a neuron (i) Where information is acquired (ii) through which information travels as an electrical impulse. (iii) Where this impulse must be converted into a chemical signal for onward transmission.

Draw the diagram showing the structure of neuron. Label the following parts : i] The part which has prominent nucleus ii] Dendrite. b] Name the part of a neuron: i] where information is acquired. ii] through which information travels as an electrical impulse.

(a) Draw the structure of a neuron and label its nucleus, dendrite, cyton and axon. (b) Name that part of a neuron (i) which receives stimulus (ii) which transmits impulse

When we touch a hot plane unknowingly then this heat is sensed by a receptor P present in oyr fingers. The receptor triggers an impulse in neuron Q which transmits the message to an organ R which is a part of the central nervous system. Here the impulse is passed on to a neuron S which in turn passes it to a yet another neuron T. The neuron T passes the impulse to a tissue U in our arm. The tissue U then contracts and pulls or hand away from the hot plate. (a) What is the name of (i) receptor P (ii) neuron Q, and (iii) organ R? (b) What is (i) neuron S, and (ii) neuron T? (c) Name the tissue U. (d) What name is given to the phenomeon in which hand is pulled quickly from the hot plate? (e) Name the effector in this whole process.
