counting the days.

gosh.

biology test is tomorrow. and i still have 7 lectures more to go. oh bio! why must you be so hard to understand. you ah, from one thing to another thing. then to another thing again. so complicating lah please.

heres' an example:

the nervous system is divided into 2 systems; the central nervous system (CNS) and the peripheral nervous system (PNS). then CNS is the brain and spinal cord and PNS is all other parts of body. after which the PNS is divided into 2 divisions; the afferent division and the efferent division. afferent division carries the sensory information while the efferent division carried the motor commands. then the efferent division is divided into 2 again; the somatic nervous system (SNS) and the autonomic nervous system (ANS). SNS controls voluntary signals while ANS control involuntary signals. and again the ANS is divided into 2; the sympathetic and parasympathetic division. sympathetic division has a stimulating effects which results in an increased in heart rate, etc while parasympathetic division has a relaxing effect which results in a decreased in heart rate, etc or in other terms; going back to normal.

i told you so. complicated. still not enough. the later-later lectures is more complicating than this which i have yet to revise on. okay i hope i'll make it through tomorrow. wish me luck people.

okay bye!
