What are the parts of your arm called?

We all know that our arms hang from our shoulders and spew forth from sleeves, but beyond that? How many of us could actually name a single part of our God-given limbs with confidence? Let’s examine each juncture more closely – we can finally tell those nosy doctors where it really hurts.

The Shoulder

Picture this: You’re standing there, minding your own business when- BAM. Someone taps on your shoulder.
Little did you know, that area is known as the “acromion process.” It’s a bony projection extending from the scapula (or shoulder blade).

Glenohumeral Joint

There is no greater pain in life than having a dislocated shoulder. That ball-and-socket joint connecting the humerus to the socket in your scapula (glenoid cavity) gives way easily. The glenohumeral joint provides an amazing range of motion by supporting rotations and allowing abduction/adduction/flexion/extension.

Upper Arm

This section is heavy lifting real estate; prepare for muscle fatigue when raising canned goods up past eye level.

Humeral Head

Attached to tendons above and below at either end of one bone lies another smaller bone which fits snugly into- okay this isn’t anatomy class let’s put it simply: just call any upper-arm regions attached to BONES ‘humeral head.’

Triceps Brachii Muscle Group

On its underside resides an elbow-shaped groove holding three beautiful “heads,” designated LONG/TOP/MEDIAL by placement along their common tendon attachment uniting them below humerus.

Lateral Head

The lateral tricep brachii (“tri” meaning 3 heads) is located farthest away from midline or median plane producing powerful extension when straightening out limb while carrying heavy objects.

Medial Head

Located on inner side of upper limb, and with a small lateral attachment overlaps the others. That’s three very active regions contributing to elbow flexing, extension as well as adduction.

Long Head

Longer than both other heads combined, it reaches over individual joints before connecting back onto bone helping out especially when needed for necessary movement involving pushing or pulling things despite resistance.

Lower Arm

Elbow Joint

The place where you tend to bang your arm and suddenly fall down in agony is called an “elbow joint.” This spot hinges like the door at grandma’s house & lets us bend our arms up closer towards face or push down more towards hips.

Common Flexor Tendon

Have you ever felt surgery-level pain after excessive writing? Blame this tendon – it connects muscle groups on inner side (sounds weird yes) while being prone to inflammation caused by carpal tunnel syndrome from strain throughout wrist.

Radial/Ulnar Bones

Attached to these bones, that meet with humerus gives strength stability aiding simply-pivoting muscles any time we turn hand outward instead of downward. Unless performed abruptly/painfully releasing stress/fracture to those areas so protect against injury!


This region contains several non-funny named parts including quite literally “finger bones” etc., but let’s pay attention strictly to “wrist/hip-bones.”


Collectively known either as either “carpals” in hands or “tarsals” in feet: These consist 5/7 rows bones order help maintain positioning , vibrancy solidity In tough movements include jumping gym workouts also bedazzling nails art designs!!

Without sounding too technical- now you can tell people exactly how complex human anatomy truly is… or how sore your triceps are from lifting weights at home during quarantine. Shout out to our bones though! They keep us standing and dancing all day long.
