What’s on the Major Muscles poster
A 11-row table: Muscle · Where · Action.
Roughly 600 skeletal muscles; these are the ones named in almost every training or anatomy context.
- Trapezius — Upper back, neck — Shrugs, rotates the shoulder blade
- Deltoid — Shoulder cap — Raises the arm in any direction
- Pectoralis major — Chest — Pushes and pulls the arm across
- Latissimus dorsi — Mid and lower back — Pulls the arm down and back
- Biceps brachii — Front of upper arm — Bends the elbow, turns the palm up
- Triceps brachii — Back of upper arm — Straightens the elbow
- Rectus abdominis — Front of abdomen — Bends the trunk forward
- Gluteus maximus — Buttock — Extends the hip — the main driver
- Quadriceps — Front of thigh — Straightens the knee
- Hamstrings — Back of thigh — Bends the knee, extends the hip
- Gastrocnemius — Calf — Points the foot down
Muscles pull; they never push. Every joint needs an opposing pair to move both ways.

- Who is the Major Muscles poster for?
- Major Muscles belongs to the Body & health section rather than to a school year, because health is not something one grade owns. Anyone learning anatomy can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Major Muscles poster?
- Muscles are named for shape, location or action. Once you notice that, the names stop being arbitrary. A wall chart earns its place by being glanceable from where the work is happening, so Major Muscles belongs on the wall where that health work actually happens, within glancing distance, rather than filed away.
- What other posters go with Major Muscles?
- Blood, Blood Types and The Body Systems sit alongside Major Muscles in the Body & health section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.BloodBlood TypesThe Body Systems
- Is the Major Muscles poster free to download and print?
- Yes. Major Muscles downloads as a free PDF with no account, no email and no watermark, like everything else in the Body & health section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Major Muscles poster print at?
- Major Muscles is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Major Muscles loses nothing.Printing guide
