Introduction Tissue just means a group of cells that together carry out a particular job in your body. There are four different types of tissue within the human body. This consists of the connective tissue‚ the epithelial tissue‚ the muscle tissue and the nervous tissue. Each of these tissues are vital for our bodies and each tissue has a very important role to fulfil. Epithelial tissue Epithelial tissue protects your body from moisture loss‚ bacteria‚ and internal injury. It is made up of cells closely packed

develop a holistic view‚ we analyse a blind man. Since this person has lost one of his senses he is much more dependant on other senses such as touch for example. 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

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

biopsychology‚ neuroscience Starting small: The Neuron neuron: a nerve cell; receives signals from other neurons or sensory organs‚ processes these signals‚ and sends signals to other neurons‚ muscles‚ or bodily organs the basic unit of the nervous system The Neuron 3 types of neurons: 1. sensory neurons: respond to input from sensory organs (skin‚ eyes‚ etc.) 2. motor neurons: send signals to muscles to control movement 3. interneurons: connect the sensory neurons and motor neurons

throughout the central (autonomic) nervous system and peripheral (somatic) nervous system where it binds to and stimulates cholinergic receptors‚ specifically muscarinic and nicotinic receptors (Mileson et al. 1998). The autonomic nervous system controls visceral functions in the body and ACh acts at muscarinic and nicotinic receptors present at effector organs such as heart‚ eyes‚ glands‚ respiratory and gastrointestinal systems. The somatic nervous system controls all voluntary functions of

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

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)
