Muscles that primarily support and move the head and trunk. They are responsible for posture and movement of the torso.

Muscles associated with the limbs that allow for movements like walking, grasping, and lifting. These include muscles in the arms, legs, and pelvic region.

A movement that decreases the angle between two body parts, such as bending the elbow or knee.

A movement that increases the angle between two body parts, such as straightening the arm or leg.

A movement away from the midline of the body, such as raising the arm to the side.

A nerve cell that transmits electrical impulses throughout the body. Neurons are the fundamental units of the nervous system.

Supportive cells in the nervous system that provide insulation, nourishment, and structural support to neurons.

The junction between two neurons or between a neuron and a target cell, where communication occurs through chemical signals.

Central Nervous System (CNS)

Composed of the brain and spinal cord, the CNS processes information and coordinates the activity of the body.

Autonomic Nervous System (ANS)

A part of the peripheral nervous system that controls involuntary functions like heart rate, digestion, and respiration.
