The baculum (also penis bone, penile bone or os penis) is a bone found in the penis of most placental mammals. It is absent in humans, but present in other primates, such as the gorilla and chimpanzee. The bone aids sexual intercourse.
The baculum is used for copulation and varies in size and shape by species. Its characteristics are sometimes used to differentiate between similar species. A bone in the penis allows a male to mate for a long time with a female, which can be a distinct advantage in some mating strategies.
The word baculum originally meant "stick" or "staff" in Latin. The homologue to the baculum in female mammals is known as the baubellum or os clitoridis or os clitoris.
Mammals having a penile bone (in males) and a clitoral bone (in females) include various eutherians:
It is absent in humans, equids, elephants, monotremes, marsupials, lagomorphs, hyenas, and cetaceans (whales, dolphins, and porpoises), among others.
Such a wide distribution among placental mammals suggests that the bone evolved early in the history of these mammals, and was subsequently lost in certain groups.
As I walk through the streets of my new city
my back feeling much better, I suppose
I've reclaimed the use of my imagination
for better or for worse, I've yet to know
but I always knew you'd be the one to understand me,
I guess that's why it took so long to get things right.
Suddenly I'm lost
On my street
On my block
Oh why, Oh why
Oh why haven't you been there for me?
Can't you see, I'm losing my mind this time?
This time I think it's for real, I can see
All the tree tops turning red
The beggars near bodegas grin at me
I think they want something
I close my eyes, I tell myself to breathe
and be calm.
Be calm.
I know you feel like you are breaking down.
Oh I know that it gets so hard sometimes.
Be calm.
I'm scared that everyone is out to get me.
"These days before you speak to me you pause."
"I always see you looking out your window."
"After all, you lost your band, you left your mom."
Now every single crack, every penny that I pass,
says I should either leave or pick it up
But with every single buck I've made
I'm saddled with bad luck that came
the moment I was baptized
or when I found out one day I'm gonna die
if only I could find my people or my place in life
a when they come a'carolin'
so loud, so bright, the theremin
will lead us to a chorus
where we'll all rejoice and sing a song that goes:
Oh be calm.
Be calm.
I know you feel like you are breaking down.
I know that it gets so hard sometimes,
Be calm.
Take it from me, I've been there a thousand times.
You hate your pulse because it thinks you're still alive
and everything's wrong
It just gets so hard sometimes
Be calm.
I don't remember much that night,
Just walking, thinking fondly of you
Thinking how the worst is yet to come
When from that street corner came a song
And I can't remember the man,
The panhandler or his melody.
The words exchanged had far exceeded any change I'd given thee.
Oh be calm.
Be calm.
I know you feel like you are breaking down.
Oh I know that it gets so hard sometimes,
Be calm.
Take it from me, I've been there a thousand times.
You hate your pulse because it still thinks you're alive
and everything's wrong
It just gets so hard sometimes
Be calm.
