The mechanism of grasp

arsanatomica:

While looking at the little screech owl, I took a series of photographs and made this gif to illustrate the of the automatic grasping action of the talons.

image

The structure of bird feet is set up so that the foot automatically grasps when the ankle joint is bent.  

image

This automatic grip allow birds to sleep while perching, and for raptors clench/grasp prey as the leg is folded on impact.

image

The mechanism of the foot is ingenious…. there’s no muscle in there at all. 

The foot is powered entirely by a pulley system of tendons. 

Two tendons that run along the back of the leg, Flexor Digitorum Longus and Flexor Hallucis Longus are responsible for the automatic grasp. The former pulls the forward facing toes, and the latter pulls on the hallux, or back toe. 

I drew a schematic diagram of these two tendons here:

image

It’s particularly interesting in raptors.

Raptors swoop down on prey with talons/legs outstretched. The impact with the prey folds the raptor’s legs against its body, causing the talons to clench automatically, tearing into the prey. The automatic grip is strong enough to kill, and is what allows many hawk species to catch and kill other birds in midair. 

The ingenuity and perfection of this mechanism is mind-blowing.

Forget the Myers-Briggs fucking personality assessment. I am dead tired of hearing if someone is an INFP or an ESLQ or whatever. I want to know if someone is melancholic or choleric. Bring back the four humors. I wanna see “Kaley, 16, phlegmatic” when I go to someone’s blog. Who is with me. Lets make this happen

here's a test i found. go wild, y'all. (im choleric.)

TRACK: if cr1tikal were a personality core

scibot9000:

I’ve noticed that the way cr1tikal talks kind of resembles an Aperture Science Personality Core

I GLaDOS-ified his voice from this video and I have to say I think it works (aside from my own lazy editing)

sci you are a beautiful fucking human being

I think there’s an extension that can remove notifications of a specific post of yours. Not sure if it applies to certain types of posts instead, though.

Yeah pssh I think I’m expecting too much from this notification system really. I’m just going to rely on the activity page instead and see how that works out!

posted 1 day ago with 1 note reblog

AW that notification setting is either all notifications or none. But I still want notifications for my original posts and replies etc! Just not everything I reblog. Might just disable all for the time being and see if it’s better or worse having to check activity for stuff. 

posted 1 day ago with 2 notes reblog
Go to Settings, Dashboard, then there should be one for “show notes” or something similar. No need for apps, Tumblr has an option itself!

AW MAN I’ve never even thought I would need it until this past month or so. Can’t believe I didn’t know about that! THANK YOU!
