Answer:
Option B, blocking alpha-1 receptors found in smooth muscle in the bladder neck and prostrate, causing them to relax
Explanation:
The subtype alpha (1A) of alpha (1) adrenoceptors are mainly responsible for expressing and contracting bladder neck, urethra and prostate thereby enhancing bladder outlet particularly in elder men (45 Years above) who have enlarged prostates.
If this alpha-1 andrenoceptors found in smooth muscle of bladder neck and prostrate are blocked somehow, then the muscles will relax and this how antiandrogens are used for treat ing benign prostatic hypertrophy
If these α1A subtype receptors are stimulated by norepinephrine, then smooth muscles are caused thereby producing a physical block at the bladder neck
Hence, option B is correct
We can use this formula to solve for acceleration of the table
F = ma
We are given with the force and the mass, so
6 N = 6 kg a
a = 1 m/s2
The change in velocity can be solve using this formula
FΔt = mΔv
6N (2s) = (6 kg) (Δv)
Δv = 2 m/s
The lateral wall of the nasal cavity is formed partly by the maxilla, partly by the ethmoid bone, and partly by the perpendicular part of the palatine bone. Further back, where the nasal cavity becomes the nasopharynx, the lateral wall is formed by the medial pterygoid plate.
