visceral pleura and outer layer called parietal pleura. While the visceral pleura does not have nocicpetors and does not give rise to the pain sensation‚ the parietal pleura can sense pain when inflamed‚ since it is innervated by numerous somatic nerves that have somatic pain receptors. Between the two layers‚ there is a space called pleural space that has a thin layer of fluid‚ and its function is to lubricate the pleural surfaces when breathing. When the surfaces become roughened and inflamed because

Synaptic Cleft Structure and Function Elizabeth Moreno Biochemistry at TMI Abstract A synaptic cleft is the space between neurons at a nerve synapse across which a nerve impulse is transmitted by a neurotransmitter—called also synaptic gap (Merriam-Webster) . This paper will utilize this simple definition in order to understand the synaptic cleft. Furthermore‚ we will explore the complex functions and the structure of the synaptic cleft. This will then allow for an in depth analysis

believe that with the two together a person experiences a personal reality that is other than the sum of the parts. Loss of sensation[edit] Many types of sense loss occur due to a dysfunctional sensation process‚ whether it be ineffective receptors‚ nerve damage‚ or cerebral impairment.

Vision loss[edit] Main article: Vision loss Degrees of vision loss vary dramatically‚ although the ICD-9 released in 1979 categorized

palsy is a disease that causes paralysis in the muscles in the face. It affects the seventh cranial nerve that travels through a narrow canal in the skull which becomes inflamed‚ swollen or compressed. Typically subsides within one to nine weeks. When Bell Palsy occurs‚ the function disrupts the facial nerve‚ causing an interruption in the messages the brain sends to the facial muscles. The affected nerve causes weakness or paralysis on one side of the face‚ which leads the mouth to droop‚ resulting

eye from scattering 5- Retina- the retina is a complex structure of photoreceptors (rods and cones) on the back of the eye. The retina’s function is that photoceptors allow us to see shape‚ movement and colour and the retinal nerve cells convert incoming light into nerve impulses. 6- Iris- the iris is a coloured part of the eye and it is a ring of muscle with a hole in the middle. 7- Lens- the lens is situated behind the iris and its function is to focus light onto the light sensitive cells.
