Sensory pathways function to provide us with information about our environment. The four parts of the sensory pathway are receptors, sensory neurons, sensory tracts, and sensory areas of the brain.
Rats share several anatomical structures with humans, including the brain, heart, and lungs. The rat brain has similar regions to the human brain, such as the cortex and limbic system, which are involved in processing sensory information and emotions. Both species possess a four-chambered heart that functions similarly in circulating blood, and their lungs exhibit a comparable structure for gas exchange. These similarities make rats valuable in biomedical research for understanding human physiology and disease.

Foot pads on the bottom surfaces of a rat's feet help them grip surfaces, climb, and navigate their environment. These foot pads have specialized ridges and structures that increase friction and provide traction, allowing rats to move swiftly and securely. Additionally, the foot pads act as sensory organs, providing feedback to the rat about the texture and composition of the surface they are on.

The sensory hairs on a rat's face are called vibrissae. These long, stiff hairs are highly sensitive and serve as tactile sensors, helping rats navigate their environment by detecting nearby objects and changes in air currents. Vibrissae play a crucial role in the rat's sense of touch, especially in low-light conditions.
because the rat is very close to the human body and to assist the learning student with identification of these structures and systems
Antennae are sensory structures that typically serve as both touch and taste receptors in insects. They detect chemical signals in the air and on surfaces, as well as physical stimuli such as wind or vibrations.
The lateral line sensory organ is the sensory pits fish use to sense movements in the water. The shark are very adapt at using these structures.
