Sponges are a group of aquatic invertebrates (animal without a backbone). There are five thousand to ten thousand known species. Sponges are multicellular organisms which have bodies full of pores and channels‚ allowing water to circulate through them. Sponges do not have nervous‚ digestive or circulatory systems. Instead most rely on a constant water

Neurons: The Basic Elements of Behavior Neurons‚ or otherwise called nerve cells‚ are the basic elements of our nervous systems. We have as many as one trillion nerve cells throughout our bodies. These cells are responsible for controlling our behavior. So what is a neuron? “A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways‚ but there is one key difference between neurons and other cells

The human beings’ nervous system consists of the brain‚ spinal cord‚ and the nerves. The nervous system enables a way for the brain to receive information about someone’s surrounding. Then‚ the brain is able to send signals to various areas of the body‚ so it can respond. Millions and millions of cells called neurons creates the nervous system. “Specialized neurons called receptors are located in the ears and eyes and the other sense

ARTHROPODS The other complex compartmentalized nervous system is found in arthropods (see the diagram). The arthropodan brain consists of three main regions: the protocerebrum‚deutocerebrum‚ and tritocerebrum. The anterior protocerebrum‚ which receives the nerves of the eyes and other organs‚ contains centres‚ or neuropils‚ such as the optic centres and bodies known as corpora pedunculata. The neuropils function as integrative systems for the anterior sense organs‚ especially the eyes‚ and in control

HYPONATRAEMIA IN THE NEUROSURGICAL PATIENT INTRODUCTION Sodium the most abundant electrolyte in the human body‚ and therefore the osmolality of body fluids is strongly dependent on its concentration. Osmolality in turn is important in maintaining homeostasis within the brain. Ironically‚ dysfunction of the brain can cause changes in sodium homeostasis. To avoid neurological deterioration‚ morbidity or mortality the sodium level must be corrected promptly. The two most common causes of hyponatraemia

Therefore the mind muscle connection has created strong links between the brain/nervous system and nerves in his fingers (braille) to ensure the human flys (recalling upon both the fight or flight theory and Darwin’s natural selection - and also a point that Tread-m touched upon in his most recent post‚ the Causality Paradigm - Cause and

The "Fight or Flight" response The flight or fight response‚ also called the "acute stress response" was first described by Walter Cannon in the 1920s as a theory that animals react to threats with a general discharge of the sympathetic nervous system.[4] [5] In response to acute stress‚ acetylcholine is released from preganglionic sympathetic nerves that innervate the chromaffin cells of the adrenal medulla. As a consequence‚ the chromaffin cells secrete the hormone epinephrine (adrenaline)
