Answer:
Most likely diagnosis is Basal Cell Carcinoma (BCC), most likely caused by years of prolonged exposure to sunlight over time.
Explanation:
Basal Cell Carcinoma (BCC) is a common type of skin cancer that develops when the basal cells that is responsible for producing new skin cells when they die, become mutated and causes the basal cell to abnormally multiply rapidly and continues to grow. The accumulation of these abnormal cells is what results in cancerous tumors that appears like ulcers on the skin. Prolong and intense exposure to the ultraviolet (UV) radiation from sunlight has been linked to the most likely cause for the mutation of the DNA in the basal cells which leads the abnormal cell growth and multiplication. People who expose themselves to the radiation of the sun for longer periods, over time, are at high risk of developing this cancer.
Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
<em>Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his </em><em><u>skin</u></em><em> to his </em><em><u>brain</u></em><em>. This information would travel via </em><em><u>GSA </u></em><em>neurones.</em>
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
I'm going with C. It may be wrong but I think it's C.
