- Los ojos traducen la luz en señales de imágenes para que el encéfalo las procese. Los ojos se ubican en las órbitas de la estructura ósea de la cabeza, protegidos por hueso y tejido graso.
- El oído utiliza huesos y líquido para transformar las ondas sonoras en señales sonoras. Música, risas, bocinas de los autos, todas llegan a los oídos como ondas sonoras por el aire.
- Receptores especializados en la piel envían señales del tacto al encéfalo. La piel consta de tres capas principales de tejido: la capa externa (epidermis), la capa media (dermis) y la capa interna (hipodermis).
- Olfato: Sustancias químicas en el aire estimulan señales que el encéfalo interpreta como olores. El sentido que detecta los olores se llama olfato. Comienza con receptores nerviosos especializados ubicados en estructuras similares a vellosidades, denominadas cilios, en el epitelio en la parte superior de la cavidad nasal.

The nervous system must receive and process information about the world outside in order to react, communicate, and keep the body healthy and safe. Much of this information comes through the sensory organs: the eyes, ears, nose, tongue, and skin. Specialized cells and tissues within these organs receive raw stimuli and translate them into signals t...
Skin consists of three major tissue layers: the outer epidermis, middle dermis, and inner hypodermis. Specialized receptor cells within these layers detect tactile sensations and relay signals through peripheral nerves toward the brain. The presence and location of the different types of receptors make certain body parts more sensitive. Merkel cell...
What are all those small bumps on the top of the tongue? Theyre called papillae. Many of them, including circumvallate papillae and fungiform papillae, contain taste buds. When we eat, chemicals from food enter the papillae and reach the taste buds. These chemicals (or tastants) stimulate specialized gustatory cells inside the taste buds, activatin...
