Muscles

• Pronator Muscle: turns the hand inward so that the palm faces downward.
• Risorius Muscle: draws the corner of the mouth out and back, as in grinning.
• Serratus Anterior Muscle: assists in breathing and in raising the arm.

Blood Circulation

• Pulmonary Circulation: takes deoxygenated blood to the lungs for oxygenation and waste removal, and returns oxygen-rich blood to the heart.

Bones

• Radius: the smaller bone in the forearm, on the same side as the thumb.

Nervous System

• Reflex: an automatic nerve reaction to a stimulus.
• Sensory Nerves: carry impulses or messages from the sense organs to the brain.

Body Systems

• Reproductive System: responsible for the processes by which plants and animals produce offspring.
• Respiratory System: consists of the lungs and air passages, enables breathing.

Cellular Structure

• Protoplasm: a colorless, jellylike substance found inside cells, containing food elements such as proteins, fats, carbohydrates, mineral salts, and water.

Nervous System

• Reflex is an automatic nerve reaction to a stimulus, which means it is a rapid and involuntary response to a specific stimulus or signal.

• The reproductive system is responsible for the processes by which plants and animals produce offspring, encompassing the entire range of biological mechanisms involved in reproduction.

Muscular System

• The risorius muscle is a specific muscle located in the mouth that plays a crucial role in facial expressions, particularly in grinning, by drawing the corner of the mouth out and back.
