- This anatomy and physiology lesson covers the hand bones and wrist bones of the appendicular skeleton. The hand consists of long bones, while the wrist bones are classified as short bones.
The hand and wrist bones include the 14 phalanges (finger bones), 5 metacarpals (palm bones), and the 8 carpals (wrist bones).
The phalanges are named after directional terms: You have the distal, middle, and proximal phalanx of each finger. The fingers have three phalanges each, except for the thumb, which has only two phalanges (distal and proximal).
The metacarpals are distal to the carpals. They are numbered 1-5, with the thumb being metacarpal 1, and the little finger being metacarpal 5.
The bones of the phalanges have a base, shaft, and head portion.
The bones of the wrist (carpals) are as follows:
-Trapezium
-Scaphoid
-Lunate
-Triquetral
-Pisiform
-Hamate
-Capitate
-Trapezoid
To remember these bones, remember the mnemonic "To Save Lives, The Physician Helps Create Treatments."

RegisteredNurseRN Hloo Mam..is there any video on coping strategy
I like this dude, he's funny but also makes things easy to remember
The most fascinating anatomy videos are only available in this channel, I am really grateful
I love the way of your presentation and it's really helpful to understand Anatomy in simple way
I am so happy I just stumbled across your channel. I am in school to be a medical assistant and this channel is absolutely amazing. What a blessing you guys are for sharing your knowledge with us. I can’t thank you enough, you have made me understand things so much better than just my lectures in class and my material from class also.
!
A thumbs 👍🏼 up for presentation.
I came here because I had forgotten my mnemonic.
Some lovers try positions that they can't handle
Scaphoid Lunate Triquetrium pisiform trapizium trapezoid capitate hamate
In anatomical position, start laterally with proximal row, move medial across carpals once, then go medial across distal row.
There's three bones that start with T. In my mnemonic "try" represents TRIquetrum, so that helps me remember that one. Trapizium almost kinda rhymes with thumb, so they are close. And Trapezoid is what's left.
100% using this, thank you!
I love your content, your videos have helped me get thur my nursing classes. Thank you, God bless
Nice work, great communications skills.
hey, quick question what is the circumference for each metacarpal bone. i tried googling but i'm afraid i can't get a precise answer.
"Most people don't know this" Proceeds to do optical illusion...I am dying over here lol
Love your videos! I'm mexican looking for work in USA. Hope to pass NCLEX and TOEFL Tests! 😊

This channel is saving my life by a thread. Haven’t been in school since 2017, trying to finish my nursing degree that I started 2012, life happens. Anyways, I took bio 201 this summer didn’t know it was gona be this hard and it’s accelerated 🫣plus I have my 4 kids home for summer vacation. 🤪🫠. This rusty brain 🧠is over extra hard but not too hard due to your videos. Thanks new sub here
This is great! Thank you so much.
So helpful!
We can remember the names of carpel bones by a formula (3TSP of HCL)
3T= trapezium, trapezoid, triquetra
S= scaphoid
P= pisiform
HCL
H= hamate
C= capitate
L= lunate
Very Knowledge full best of luck sir
Splendid!
Many thanks sir
You're amazing
Question please, is it really seldom to encounter penulate dislocation and scaphoid fracture?
Perfect
Very Good 💻
Thisis.the.great 👌🙏🙏
Mam send each lectures notes on website
Wow I got everything thank you sir 💖 really helpful video
I like your contest
