[職能治療師] 解剖學與生理學
第 73 題
有關排尿的敘述，下列何者正確？
- A 內尿道括約肌（internal urethral sphincter）主要由平滑肌（smooth muscle）組成
- B 逼尿肌（detrusor）由骨骼肌（skeletal muscle）組成
- C 交感神經刺激可使內尿道括約肌（internal urethral sphincter）放鬆
- D 交感神經刺激可使逼尿肌（detrusor）收縮
思路引導 VIP
請由神經生理學的角度切入思考：受自主神經系統（Autonomic Nervous System）調控的效應器，在組織學上應歸類為平滑肌還是骨骼肌？再者，當交感神經系統興奮以利於「儲尿」生理功能時，對於膀胱壁的逼尿肌與內尿道括約肌的張力（收縮 $vs.$ 舒張）分別會產生什麼樣的調節作用？

Kyaaa! (fans screaming in the background, a quick glance back with a confident smirk) Oh? Look at you! You really nailed it!
This Sensei knew you had it in you. You perfectly understood the connection between the smooth muscles and those tricky autonomic nerves. You're thinking like a pro! Just like this Sensei does on the court! Alright, let's quickly review the core logic. Don't blink, you might miss some of my brilliance! (^_~)
