Bones of the Human Skeleton
Curious about your anatomy? Impress you friends by grabbing their ulna and letting them know their manubrium is showing.
Ok, lets start at the top – your head is made up of 8 cranial bones and 14 facial ones, but the whole thing can generally be referred to as the cranium.
You’ve got 12 pairs of ribs, the bottom 2 pairs referred to as “floating” because they don’t directly articulate with the sternum, which is the long, flat bone in the middle of your chest (your breast bone). The top of the sternum is called the manubrium and the bottom is the xiphoid.
Fun fact: the bottom 2 ‘floating’ ribs can be surgically removed without many consequences – Marilyn Manson had this procedure done so he could do some interesting things…..
Also on the torso, there’s the scapulas (shoulder blades) and clavicles (collar bones).
The spine is made up of 24 individual vertebrae, which are named for their position – there are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral then 4 fused vertebrae which form the tailbone.
Fun fact: the sacrum bone is called this because it was traditionally considered sacred – because this is the only bone that survives if you burn a human body.
This sacral region of the spine articulates with the pelvic bone. The top of the pelvis is known as the ilium, while the bottom is the ischium.
The lower limb: the femur (thigh bone) articulates with the pelvis up top and the tibia and fibula down below. The tibia and fibula are the bones in the calf. The femur and tibia also interact with the knee cap, which is called the patella. Down at the ankle, the fibula and tibia form a mortise, into which fits the talus bone. The talus sits on top of the calcaneus, which is your heel bone. Your midfoot is made up of the navicular, the cuboid and 3 cuneiforms. Then comes your metatarsal bones, which are long and thin, and these articulate with the phalanges, which are your toes, essentially. Each toe has 3 phalanges, except the big toe (also called the hallux) which only has 2. The upper limb: your upper arm is the humerus, which articulates with the radius and ulna at the elbow. The bones of the hand are: scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate and hamate. A commonly used mnemonic to remember these bones is: “Some Lovers Try Positions That They Can’t Handle”. These carpal bones articulate with the matacarpals (which are the equivalent of metatarsals in the foot) and then meet up with the phalanges – your fingers! Just like the toes, each finger has 3 phalanges, except for the thumb which has 2. Fun fact: the only bone which is not joined to any other bone is the hyoid bone in the throat – forensic investigators can tell is someone has been strangled if this bone is broken. Sound is conveyed in the ear by 3 tiny bones called the hammer, anvil and stirrup. The average person has around 206 bones in their body, but you might have some extra – each person is different and a lot of people have “accessory bones” in strange places like their hands and feet! So there you go – a brief overview that you can impress your friends with! Have fun!
