Question
**Where is the deltoid?**

The image is a diagram of the human muscular system showing the front view of a male figure. Various muscles are labeled with letters:

- **A**: Located on the shoulder, likely indicating the deltoid muscle.
- **B**: Located on the upper arm.
- **C**: Located on the thigh.
- **D**: Located on the lower leg.
- **E**: Located on the side of the head/neck area.
- **F**: Located on the side of the neck.
- **G**: Located on the chest area.
- **I**: Located on the shin area.

The deltoid muscle is typically found on the shoulder, corresponding to label **A** in this diagram. The diagram helps in understanding the location and labeling of different muscles in the human body.

The image shows a detailed anatomical diagram of the muscles of the head and neck. It is labeled with letters indicating various muscles. The question, "Where is the orbicularis oculi?" is posed at the top.

### Description of the Diagram:

- **A:** Indicates a muscle at the top of the head.
- **B:** Indicates a large muscle at the back of the neck.
- **C:** Points to a muscle above the cheekbone.
- **D:** Indicates a muscle near the eye area where the orbicularis oculi is typically located.
- **E:** Points to another muscle around the eye region.
- **F:** Labels a muscle near the nasolabial fold.
- **G:** Indicates a muscle extending from the nose toward the cheek.
- **H:** Points to a muscle above the upper lip.
- **I:** Marks a muscle in the cheek area.
- **J:** Indicates a muscle near the corner of the mouth.
- **K:** Points to a muscle below the lower lip.
- **L:** Indicates a muscle running down the side of the neck.
- **M, N, O:** These label muscles further down the neck.

The orbicularis oculi is a circular muscle around the eye socket responsible for closing the eyelids. Based on typical anatomical location, labels D and E are potential points for the orbicularis oculi, highlighting the muscles surrounding the eye area.
