Internal Thoracic Artery

We've learned about the oxygenated blood in the subclavian artery,
and how it branches into the vertebral artery in your neck to give blood to your brain.

Another branch of the subclavian artery is called the internal thoracic artery.

This artery brings blood to your chest.

Vertebral Artery

We've learned that the oxygenated blood leaves the heart at the aorta, goes to the aortic arch, and then to the subclavian artery.

The subclavian artery then splits into some other arteries, and one of them is called the vertebral artery.

The vertebral artery goes right into your spine and then goes up your neck to help give more blood to your brain, along with the internal carotid artery.

Subclavian Artery

We just learned about the External Carotid Artery.

We've learned that the aorta carries oxygenated blood from the heart, up to the aortic arch and then to the carotid arteries to bring blood to the neck and head.

The aortic arch also has two other arteries called the left and right subclavian arteries.

They carry the oxygenated blood to your left and right arms.

Aortic Arch

We've learned that the big tube leaving the heart is called the aorta, and the first part of the aorta that goes up is called the ascending aorta.

After the ascending aorta goes up, it turns toward the middle of your body by your trachea.
That curved part where it turns is called the aortic arch.

There are some smaller tubes that come out of the aorta at the arch and go up toward the neck and head, and then the large aorta tube turns to go downward.

Ascending Aorta

We've learned that the left ventricle chamber of the heart pushes the good oxygenated blood to all the parts of your body, and the big tube leaving the heart is called the aorta.

The aorta starts by going up toward your head, and then it turns and goes down towards your belly area.
The part where it is going up is called the ascending aorta.
The word ascending means going up.

Pulmonary Vein

We've learned that our blood gets filled up with good oxygen in the capillaries down by the lungs.

After the tiny capillaries are filled up with good oxygen, they connect to larger tubes called veins, and the blood flows toward the heart.

The veins that connect the capillaries to the heart are called the pulmonary veins.

Rectus abdominis

Let's keep learning about the muscles in the human body!

Last time we learned about the latissimus dorsi

Next up is the rectus abdominis.
These are the muscles in the front of your stomach, also called your abs or abdominal muscles.
You use them when you do bend forward, like you're doing a sit up.


(from: wikipedia - rectus abdominis muscle)

Since these muscles sometimes look like six bumps on your stomach,
some people call them a six pack.

Latissimus Dorsi

Let's keep learning about the muscles in the human body!

Last time we learned about the trapezius

Next up is the latissimus dorsi.

These muscles are sometimes just called lats.

You use your lats when you pull your arms down from the sky like doing a chinup,
when you pull your arms toward your body like opening a door,
and when you pull your arms up from the ground like picking something up.

(from: wikipedia - latissimus dorsi)

Trapezius

Let's keep learning about the muscles in the human body!

Last time we learned about the pectorals

Next up is the trapezius.

The trapezius, which are sometimes just called traps
are used when you lift your arms over your head,
when you try to touch your elbows together behind your back,
or when you fold your hands behind your back.

(from: wikipedia - trapezius muscle)

Pectorals

Let's keep learning about the muscles in the human body!

Last time we learned about the deltoids

Next up is the pectorals.

The pectorals, which are sometimes just called pecs
are used when you do pushups, when you clap your hands together, or flap your arms like wings.

Pelvis, hip bone

We just learned about the Coccyx Bone.

At the base of the spine, the sacrum is connected to the pelvis, or hip bone.

The pelvic bone is made up of three parts, the ilium, ischium and pubis.

(from: wikipedia - hip bone)

The ilium is the hip bone part you can feel on your side.
The ischium is the bone that you sit on, right on either side of your bottom.
The pubis is right in the middle below your tailbone.

Coccyx

Last we learned about the sacrum which connects to the lumbar vertebrae.

Below the sacrum, and the last part of the spine
is the coccyx (sounds like cock-six)
Sometimes it's also called the tail bone.

It is made up of three to five bones that curve forward toward the front of your body.



(from: wikipedia - coccyx)

Sacrum

We just learned about the Distal Phalanges.

We've learned before about most of the bones in your spine,
the cervical vertebrae, thoracic vertebrae, and lumbar vertebrae.

There are two more parts on your spine at the very bottom.
The first one is called the sacrum, a somewhat large triangle shaped bone right in the middle of your hips.

sacrum by itself:

sacrum shown where it is in between the hip bones:


We'll learn about the other part next Tuesday!

False Ribs

We just learned about the Pectoral Girdle

The lower five ribs are called the false ribs.


(From: Wikipedia - false ribs)

The upper three false ribs are called the vertebro-chondral ribs, because they connect from the vertebrae to the rib above them.

The lower two false ribs are called the floating ribs or vertebral ribs because they only connect to your vertebrae, and the other end is just floating out there.

Pectoral Girdle

The clavicle and scapula together make up what is called the pectoral girdle.


(From: Wikipedia - pectoral girdle)

Clavicle and Scapula

We just learned about the Esophagus

The bones on the upper part of your shoulder are called the clavicle (or collarbone) and the scapula (or wingbone).

The clavicle is the bone in the front that goes from your neck to your shoulder.
It is connected to your sternum (middle of your chest) and your scapula.

The scapula is the bone in the back that sticks out like a wing, and connects up to the back of your shoulder.
It is connected to your clavicle and your upper arm bone.


(From: Wikipedia - Clavicle)

Lumbar Vertebrae

We just learned about the Thoracic Vertebrae.


The five vertebrae in your lower back are called the "lumbar" vertebrae.

To help remember that, think of your back hurting so you put your hand on your lower back, and you have five fingers on your hand.
L is for lower and lumbar, and five fingers for five vertebrae!

(from: wikipedia - human vertebral column)

Thoracic Vertebrae

We just learned about the Cervical Vertebrae.

The middle part of your spine is called the Thoracic Vertebrae.
Remember that your ribs are called the Thoracic Cage, and your Spine is made up of vertebrae.

(from: wikipedia - thoracic vertebrae)

Cervical Vertebrae

We just learned about the True Ribs

The upper seven vertebrae that connect your head to your shoulders are called the cervical vertebrae.


(From: Wikipedia - cervical vertebrae)

True Ribs

We just learned about the Thoracic Cage.

The upper 7 ribs are called the True Ribs or Vertebrosternal Ribs



(From: Wikipedia - true ribs)

If this is hard to remember, you can try to remember that they connect your vertebrae in back to your sternum in front.
Vertebrae + sternum = Vertebrosternal
