You’ve probably seen it a thousand times—that weird little bump on the front of a guy's neck that bobbles up and down when they swallow. We call it the Adam's apple. But honestly, most people have no idea what it’s actually there for. Is it a bone? Is it just for show? And do women actually have one too, or is that just a myth?
Let's get into the nitty-gritty.
The scientific name for this thing is the laryngeal prominence. Basically, it’s just a chunk of thyroid cartilage that sits right in front of your larynx, or your voice box. If you think of your throat as a high-traffic highway for air and sound, the Adam's apple is essentially the guardrail.
So, what does an Adam’s apple do anyway?
The primary job of the Adam’s apple is protection. It’s not there to help you talk or swallow, at least not directly. Its main gig is acting as a protective shield for your vocal cords.
Your vocal cords are incredibly delicate. They're these tiny, thin folds of tissue that vibrate to create sound. Without that hard "armor" of cartilage in front of them, even a minor bump to the neck could cause serious damage to your ability to speak or breathe.
It’s basically a housing unit
Think of the Adam's apple like a house. Inside that house, your vocal cords are doing all the work. The cartilage "walls" (the Adam's apple) just make sure the roof doesn't cave in.

Beyond protection, some researchers think the size of the Adam’s apple might help resonance. When the larynx grows larger during puberty, the cartilage has to expand to fit it. This is why you see a direct link between a huge Adam's apple and a deep, booming voice. The bigger the "instrument," the lower the sound.
The Puberty Factor: Why is it bigger in men?
Everyone is born with this cartilage. Little boys and little girls actually have pretty much the same neck structure. But once puberty hits, testosterone enters the chat.
In males, testosterone causes the larynx to grow significantly. As the voice box gets bigger, the thyroid cartilage has to tilt forward to make room. This creates a sharper angle—usually around 90 degrees in men. In women, the angle stays much wider, around 120 degrees, which is why it stays flat and mostly invisible.
- Men: Sharp angle = prominent bump.
- Women: Wide angle = smooth neck.
It’s a secondary sex characteristic, sort of like facial hair or broader shoulders. It doesn't actually do anything different in a man than it does in a woman; it’s just more obvious because the "machinery" inside is larger.
The "Women Don't Have Them" Myth
I hear this all the time, and it’s just flat-out wrong. Every human being has an Adam's apple. If you didn't have one, your voice box would be exposed and your throat would likely collapse. The only reason we don't "see" them on most women is because of that wider angle I mentioned and, frankly, different distributions of body fat in the neck.
Sometimes, you’ll see a woman with a very visible laryngeal prominence. It doesn't mean anything is wrong. It could just be genetics, a very lean neck, or naturally higher testosterone levels during puberty. It's just anatomy.
When should you actually worry about it?
Since the Adam’s apple is just a piece of cartilage, it shouldn’t hurt. It shouldn’t suddenly grow, and it shouldn't feel "stuck."
If you notice a bump in that area that isn't the Adam's apple, or if your Adam's apple seems to be shifting, it might actually be your thyroid gland. The thyroid is a butterfly-shaped gland that sits just below the Adam’s apple. When it gets inflamed—a condition called a goiter—it can look like a massive Adam’s apple.
Red flags to watch for:
- Pain while swallowing: Cartilage doesn't have nerves that should hurt like that.
- Rapid growth: If that bump gets bigger over a few weeks, see a doctor.
- Hardness: It should feel firm but slightly "give" if you (gently!) touch it. If it feels like a literal rock, get it checked.
- Hoarseness: If your voice changes and stays that way, it’s usually an issue with the vocal cords inside the cartilage.
The "Tracheal Shave" and Aesthetics
Because the Adam's apple is so closely tied to how we perceive "masculinity," it’s a big focal point in gender-affirming surgeries.
There’s a procedure called a chondrolaryngoplasty, or more commonly, a tracheal shave. Surgeons literally go in and shave down the protruding part of the cartilage to create a smoother neck profile. It’s a delicate surgery because if they shave too much, they could hit the "anterior commissure"—the spot where the vocal cords actually attach. Mess that up, and your voice changes forever.
Actionable Insights: Checking Your Own Neck Health
Knowing what’s normal for your body is the best way to catch issues early. Here’s how to do a quick "self-check" of your laryngeal area:
- The Swallow Test: Take a sip of water while looking in the mirror. Your Adam’s apple should move up and then back down smoothly. If it hitches or looks lopsided, it’s worth a mention to a GP.
- Feel for Symmetry: Gently feel the cartilage. It should be relatively centered.
- Check the "Notch": There’s a little V-shaped dip at the very top of the Adam’s apple (the superior thyroid notch). Finding this is a great way to orient yourself if you’re trying to locate your pulse or check for swollen lymph nodes nearby.
- Voice Monitoring: If you find yourself clearing your throat constantly or feeling like there’s a "lump" that won't go away (globus sensation), it’s usually stress or acid reflux, not the cartilage itself.
The Adam’s apple is a simple, effective piece of biological engineering. It’s a shield, a resonance chamber, and a landmark for surgeons. Whether it sticks out or stays hidden, it's doing the heavy lifting of keeping your voice safe every time you speak.
