Next up, we have anatomical terms for the back of the trunk. Okay. Same disclaimer as always. Check your notes. Every anatomy class is a little bit different. You want to make sure you're learning the words that are going to be on your test. Okay. First up, we have scapular. Scapular is the region of the shoulder blade, and the scapula is the bone that is your shoulder blade. Now both scapular and scapula come from the Latin meaning spade or shovel. We don't know why. It could be that a human scapula kind of looks like a small shovel or it could be that a very long time ago people used animal bones as digging tools and a big old animal scapula would be a particularly good digging tool. We don't know what's right. For our purposes, it doesn't matter. Scapular, shoulder blade. Next, we have vertebral. Vertebral is the spine, and the spine is made up of bones. Those bones are called vertebrae. So the bones of the spine are vertebrae. The region of the spine is the vertebral region. Next, we have lumbar. This is one you may be familiar with. Lumbar is the lower back. If you ever bought an office chair, you want to make sure you get an office chair with nice lumbar support because it's gonna support your lower back, lumbar lower back. Moving down, we have gluteal. Gluteal is your glutes or your buttocks. Your gluteus maximus is the big muscle in your rear end. So gluteal, glutes or buttocks. Next, we have metacarpal. Now metacarpal isn't on the trunk, but in anatomical position, it's in the back. So we're gonna do it here. Metacarpal is the bones of the hand. The metacarpal region comes from 2 root words. Meta means after and carpal means wrist. So when you go after the wrist, you reach the bones of the hand. Metacarpal, bones of the hand. Finally, on this side, we have perineal. Perineal is the small region between the anus and the genitals. Now you may have a slang term that you use for this region. If it helps you remember it, I encourage you to link those 2 in your mind. For me, I like to remember it because perineal kind of sounds like perianal, and the perineal region is next to the anus. The root word peri actually means near or around, so perianal would mean near the anus. That's not where perineal comes from, but it helps you remember it. Perineal, the small region between your anus and your genitals. Over here, we have olecranon. Olecranon is the back of the elbow. Now olecranon comes from 2 Greek words. First, we have ole, which means elbow in Greek, and second, we have cranium, and cranium means head. So if you look at the back of your elbow, right, you have that bump on there, that bone that sticks out. That's the head of your elbow. The head of your elbow would be the olecranon region. Olecranon, back of the elbow. Now finally, here we have sacral. Sacral is going to be the bottom of the spine. Your spine comes down to the sacrum. The sacrum meets up with the pelvis, and that's what connects your pelvis to the spine, the sacral region. Now sacral and sacrum comes from the Latin meaning sacred. We're not exactly sure why. It could be that in animal sacrifices, this bone, the sacrum, was considered particularly sacred, and so it was used there. I've also heard that when a skeleton decomposes, the sacrum is the last bone to rot. I don't know if that's true, but if it is, people might think that that is a sacred bone. So the sacrum is a sacred bone. Sacral, the bottom of your spine. Okay. That means we've learned 8 more terms. We are on our way. I'll see you in the next video.
Anatomical Terms for the Back - Online Tutor, Practice Problems & Exam Prep
Created using AIUnderstanding anatomical terms for the back of the trunk is essential. Key regions include scapular (shoulder blade), vertebral (spine), lumbar (lower back), gluteal (buttocks), and sacral (bottom of the spine). The olecranole refers to the back of the elbow, while perineal denotes the area between the anus and genitals. Metacarpal pertains to the bones of the hand. These terms are foundational for studying human anatomy and facilitate effective communication in medical contexts.

Anatomical Terms for the Back Example 1
Video transcript
This example wants us to take those anatomical terms that we just learned and try to identify some very specific muscles or fascia in the body. Now you probably know what muscles are. You may not know that fascia is connective tissue that surrounds muscles or connects muscles to other tissue in the body. You don't need to know that for this chapter. We'll learn all about it when we do muscles.
Okay. First off, we have the gluteus maximus. Where might that be? Well, gluteus maximus is in the gluteal region. The gluteal region, or your gluteus maximus, is the large muscle of your rear end. We're going to say it's in the buttocks. So the gluteus maximus, the big muscle of your butt. Next, we have the transverse peroneal muscle. Where might that be? Alright. Transverse peroneal. Keyword, peroneal. We said peroneal was the small region between the anus and the genitals. So, I'm just going to write that: between anus and genitals. Next up, we have the levator scapulae. Think where that may be. Alright. Keyword there, scapulae. Scapulae sounds like scapular. Scapular is the shoulder blade.
Finally, we have what I think is a bit of a tricky one, the thoracolumbar fascia. Where might that be? Okay. This word here actually has two roots in it. First, we have thorax, the thoracic region, and second, I see lumbar, which is known as the lower back. So, the thoracolumbar fascia is a bunch of fascia connective tissue that connects muscles to your spine in your back. With that, we have some more practice problems below. Give them a try.
