molecules‚ their ligands; responsible for taste and smell. Also monitor internal environment‚ such as CO2 levels in blood. Olfaction is the sense of smell. Olfactory sensors are embedded in epithelial tissue at top of nasal cavity (in vertebrates). Axons extend to the olfactory bulb in the brain‚ dendrites end in olfactory hairs on the nasal epithelium.

are necessary to stimulate different types of neurons. A neuron is made up of three basic parts: a cell body (soma) that contains the nucleus‚ dendrites‚ which are branches off the cell body that are there to receive impulses and signals and a long axon that carries impulses away from the body and on to surrounding neurons. The fluid inside a neuron is separated from that outside by a cell membrane that contains particles known as ions. When a neuron is stimulated a change in cell potential occurs

In the following essay I will be looking at both sides of the debate of whether neuroscience replaced psychology in explaining behavior. To begin with we must firstly understand what exactly neuroscience is and what it entails. It is generally defined as the study of how the nervous system develops‚ its structure and the functions it carries out. Neuroscientists study the brain and how it impacts on human beings behavior and cognitive functions. The study also looks at what occurs when things don’t

What is an action potential? To put it simply‚ it is a message that is sent down the nervous line. The message is written and is sent from the central nervous system. That message is addressed to muscles or glands. This essay will explain what happens before‚ during‚ and after an interneuron action potential. To accurately define an action potential‚ it is part of the incredible course of events that occur during the firing of a neuron. When a neuron is not firing signals‚ the interior of the
