Does venule have a smooth muscle layer? the pics I've seen on google are two types:

1- they have: 2- they don't have

what's the story?

it's not homework, think ...

The 1 types are right. Both areterioles and VENULES have Tunica media which is made up of smooth muscle+(elastin) and they have Tunica interna(simple squamous). They lack Tunica externa. Hope it helps!

    $\begingroup$ Thanks for the answer. What is the source for this information? Also, you have not addressed the question of WHY there is a difference among different authors in this matter. Why do some authors say there is smooth muscle and some say there isn't? $\endgroup$ – Adhish Jul 3 at 14:17

  • $\begingroup$ Tunica externa of VENULES is fused with sorrounding tissue, some authors consider Tunica externa as it's part some don't. Here's a link you would like to read - histology.leeds.ac.uk/circulatory/veins.php $\endgroup$ – Samarth Agnihotri Jul 4 at 16:49
