We're talking about BRACHIORADIALIS this week- a forearm muscle!
Aka " the beer drinking muscle" or the "hitchhiking muscle" (you'll know why soon!)
BRACHIORADIALIS starts just above your elbow joint and travels down the "thumb side" of your forearm attaching to the tip of that arm bone (the radius!) at the wrist!

BRACHIORADIALIS starts just above your elbow joint and travels down the "thumb side" of your forearm attaching to the tip of that arm bone (the radius!) at the wrist!
Official attachment points:
from the proximal 2/3 of the lateral supracondylar ridge of the humerus TO THE styloid process of the radius.
BRACHIALIS MUSCLE ACTIONS:
1. FLEXION of the Forearm at the Elbow (aka: bending your arm >
because the muscle CROSSES the elbow joint it can do this!) - elbow
joint aka "humero-ulnar joint"
2. PRONATION of the Forearm at the radio-ulnar joint* (aka: flipping your palm Down)
3. SUPINATION of the forearm at the radio-ulnar joint* (aka: flipping your palm UP! - in school we were taught "SOUPination" (as in to hold a hot bowl of soup would you would be "palms up" as opposed to Pronation (palms down)
Here's a VISUAL of all 3 actions:
*RADIO-ULNAR joint: this is the point just below your elbow where your two forearm bones meet and cross > the radius and the ulna bone)
