Within the body‚ there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured

Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system‚ a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

These important ions help regulate homeostasis in our bodies‚ as well as allowing us to move‚ absorb food‚ heal‚ and reproduce. Understanding how these ions work within our bodies will allow us to comprehend the physiology behind muscle contraction‚ nerve signaling and cell signaling. Upon learning about calcium‚ we already briefly know how

The article “The Shaking Women or A History of My Nerves” is an intriguing piece to read as it captures the idea of what it’s like struggling with an unknown disorder. The author‚ Siri Hustvedt‚ provides readers with a vision of her journey through the search of a diagnosis for her mysterious‚ shaking episodes. While on her journey‚ the author provides readers with an insight on various theoretical paradigms‚ historical views of abnormal behaviours and disorders as well as personal experiences living

The nerve impulse The information is transmitted by polarity changes in the membranes of cells due to the presence of neurotransmitters that alter the ionic concentration inside the cell. Moreover‚ inside the neuron proteins and ions are negatively charged . This difference in ion concentration also produces a potential difference between the outer membrane and within the cell . The value reached is about -70 millivolts (negative inside with respect to the value of positive charges outside

Craniosacral Therapy and Occupational Therapy Cranial sacral therapy is a very gentle hands-on technique that is usually used to enhance calming of the nervous system. The normal composition of this system includes the brain‚ spinal cord and surrounding tissues‚ which are all bathed in the cerebrospinal fluid. This mode of therapy is usually gentle and enhances the fluid nutrition of the brain and the spinal cord thus improving an individual’s energy and mobility‚ and decreasing the effects of stress

Optic Nerve The optic nerve is located in the back of the eye and is also called second cranial nerve and cranial nerve II. the optic nerve is to transfer visual information from the retina to teh vision centres of the brain via electrical impulses. It is made up of ganglionic cells or nerve cells and consists of more than 1 million nerve fibres . Our blind spot is caused by the absence of specialised photosensitive/light-sensitive cells or photoreceptors; the part of the retina where the optic
