Homework Answers
1. Thyroid secrete harmones T3 & T4. Remaing options are organs and 4 option is vestigial organ they do not secrete hormones
2. Mortor neurons they carry the impulse from brain to all the parts of the body.
3. Synapse it is a junction between two neurons where neurotransmitters play an important role in conduction of impulse
4 Sensory neurons they conduct impulse from sense organs to brain& Spinal cord
5.Long range signalling used for communication in cells
6 skin does not produce hormones but help in release of hormones
7 Pitutary produce two types of fertility hormones namely FSH and LH
8
9 Dentrides and Axon Dentrides help in attachment to another neuron where as Axon helps in conduction of impulse in it and it is surrounded by lipid layer called myelin sheath
