Physiology Exam

Assalamualaikum :)

Hari ni exam Physiology.

macam Perang Tabuk :))

xpe. belajar utk ilmu kan? teruk la kalau doctors sendiri tak master human physiology.

***

nak tau satu fakta menarik? pada saya menarik laaa

kalau kita panas ataupun kita undergo any sympathetic situations, kenapa kita berpeluh dan kulit kita kemerah-merahan?

bukankah kalau sympathetic stimulation akan menyebabkan vasoconstriction? tapi kenapa vasodilation yang terjadi?

the answer is, in our skin, there are sympathetic cholinergic fibers that innervate sweat glands and stimulate sweating. and when the sweat glands are stimulated, they produce KALIKREIN ENZYME that can convert kinongen to KININ.

FYI, kinin is an active vasodilator !

*vaso = vessels*

jadi patutla bila kita berpeluh, automatically muka pun merah-merah, vasodilation rupanya.

ps. biochem biochem. semoga sempat cover semua soalan. hopefully semua neurons dalam otak ni terus hasilkan action potential agar cepat absorb dan hafal segala bagai structures.

pps. Vietnam Airlines pun jadilah. :) 11 days to go <3
