- # 114 Control And Co-ordination Syllabus 2016
15.1 Control and co-ordination in mammals 15.2 Control and co-ordination in plants All the activities of multicellular organisms require co-ordinating, some very rapidly and some more slowly. The nervous system and the endocrine...
- #108 Homeostasis In Mammals
In the body of an animal conditions such as water concentration, temperature, and glucose concentration must be kept as constant as possible. Control systems that keep such conditions constant are examples of homeostasis; this is the maintenance of constant...
- Week Two: Evo Devo Thoughts
I was genuinely surprised to learn about the role of master control genes in the evolutionary process. I always thought (as many people do, I think) that the development of a new trait required a mutation in a gene. And, honestly, I could never figure...

Comparison between neural control and hormonal control
Neural control and hormonal control:
Major differences
| Neural control | Hormonal control |
| 1. Its action is always quick | May be quick acting or slow acting |
| 2. Information are transmitted as electrochemical nerve impulses | Information are transmitted as chemical messengers (hormones) |
| 3. Impulse transmission occurs through nerve fibres | Hormonal transmission occurs through blood |
| 4. Information would be towards a specific direction (effector organ or CNS) | Hormones are released in general blood circulation from where taken by specific receptor. |
| 5. It is suitable for quick reactions like reflexes. | It is suitable for long-term changes such as maintenance of pregnancy. |
| 6. Short time effect | Long lasting effect |
