Nervous system and the endocrine system
Brain and spinal cord
The three main parts of the brain are:
1. Cerebrum- The cerebrum is most of your skull. It controls/ involves your remembering, problem solving, thinking, feelings and movement.
2. Cerebellum- The cerebellum is under your cerebrum at the back of your head. It controls your balance and coordination.
3. Brain stem- The brain stem is in front of your cerebellum and under the cerebrum. The brain stem connects the brain to the spinal cord and controls automatic functions such as: breathing, digestion, blood pressure and heart rate.
Your nervous system is made up of a network of cells called neurons which transmit information in the in the form of electrical signals to your brain. Your brain has around 100 billion neurons, and each communicates with thousands of others, this is as many connections as in the world’s telephone system, it is also the biggest machine on the planet. Neurons communicate with each other at special junctions where chemicals help to bridge the gap between one neuron and the next.
The glands of the endocrine system
Glands and hormones they produce:
1. Hypothalamus and Pituitary Gland-
Hormones: Growth hormone, anti-diuretic hormone, adreno corticotrophic hormone, thyroid stimulating hormone.
2. The Pineal Gland
3. The Thyroid Gland
4. The Parathyroid Glands
5. The Adrenal Glands
6. Islets Of Langerhans (Pancreas)
7. Ovaries (Female)
8. Testes (Male)
Your endocrine system tells you what to do. It helps regulate and maintain various body functions by making and releasing hormones. Without your endocrine system you wouldn’t be able to grow, and get bigger, your body wouldn’t know that it’s time to begin puberty etc.
