t is plugged into the brain. The brain then processes these impulses where they are transformed into an image in our mind. What our minds experience is an image of the outside world similar to how a television projects an image captured by a television camera. In Putnam’s thought experiment‚ you imagine that your brain has been severed from the nerves connecting it to your senses (eyes‚ ears‚ nose‚ etc.) and has been removed from you skull and placed in a vat filled with the nutritional fluid

eye controls how much light it receives by reducing and enlarging the size of the pupil. A camera lens has to be adjusted to receive the proper amount of light. Cameras Have no Blind Spot • the human eye has a "blind spot" located where the optic nerve leaves your eye and connects to the brain. At that connection point‚ the eye can’t see anything. A camera lens doesn’t have a connecting point like this and has no blind spot. Table: Similarities & the Difference between Camera and Human Eye Function

have knowledge of the image as a pixelate map of activated and non-activated on the retina. Each photocell have a nerve that connects to a precise area in the visual cortex of the brain. When any photocells becomes activated‚ they send a nerve impulse to the brain‚ while the photocells that are not activated do not send any impulse to the brain. While the brain receive a collection of nerve signals from the eye‚ each signals are interpreted‚ and reconstructs the pixelate map. The brain then interprets

CELL ULTRASTRUCTURE CELL ULTRASTRUCTURE Cells are the smallest functional units of the body‚ (Waugh‚ A. and Grant‚ A.2010). Most cells are microscopic. The largest cell in the body is the female ovum. The erythrocyte is the smallest cell. The longest cell is the neuron. Cells group together to form tissues‚ each of which has specialised function. Different tissues group together to form organs. Organs are group together to form organ systems‚ each of which performs a particular function that

which causes muscle fatigue. (Mullick) During muscle fatigue‚ feedback of nerve impulses from the fatigued muscles interrupts on a part of the reticular formation and causes a hang-up of voluntary effort. (Amussen) It is important to understand that muscle fatigue results from metabolic reasons and not structural changes in your muscle. Peripheral muscle fatigue involves the motor units‚ such as motor neurons‚ peripheral nerves‚ motor endplates‚ and muscle fibers. There are two different sites where

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 Effect ).

neurotoxin A has another affect on another process that occurs during nerve signaling and the transportation of chemical signals that cause muscles to contract. Botox prevents or disrupts the path of a neurotransmitter from leaving the cell‚ which is essentially the disruption exocytosis (Botulinum toxin‚ 2013). By blocking the neuromuscular junction‚ the neurotransmitter is not allowed to leave the cell and transmit a nerve impulse to the muscle‚ causing it to contract (Medical Device Source‚ 2013)
