Nervous & Endocrine Systems!
By Rachael, Taylor and Emily.
How Does the Nervous System Work?
The nervous system is a network of cells called neurons which transmit information in the form of electrical signals. Your brain has around 100 billion neurons, and each communicates with thousands of others – as many connections as in the world's telephone system, 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.
How Does the Endocrine System Work?
In general, the endocrine system is in charge of body processes that happen slowly, such as cell growth. Faster processes like breathing and body movement are controlled by the nervous system.
The foundations of the endocrine system are the hormones and glands. These hormones transfer information and instructions from one set of cells to another.
The Adrenal Gland.
The Adrenal gland produces cortisol and catecholamine hormones.
The Pituitary Gland.
The Pituitary gland produces the growth hormone, the thyroid stimulating hormone, the adrenocorticotropic hormone, Luteinizing hormone, Follicle stimulating hormone and Prolactin hormone.
The Thyroid Gland.
The Thyroid gland produces Tyroxine and Tri-iodothyronine.
The Testicle Gland.
The Testicle gland produces the Testosterone hormone.
The Thymus Gland.
The Thymus gland produces T-cells.
The Ovaries.
The Ovaries produce oestrogen and progesterone hormones.
