What are the senses?
What are the senses?
The five traditional senses are touch, taste, smell, sight, and hearing. Balance is also considered a sense.
How do senses work?
How do senses work?
Senses rely on receptor cells or groups of receptors that form a sense organ. These receptors respond to stimuli like heat, light, pressure, and chemicals.
How are stimuli processed?
How are stimuli processed?
Receptors convert stimuli into electrical impulses that travel along neurons to the brain. The brain interprets these impulses, giving rise to sensations.

Study Notes
- Humans were said to have five senses: touch, taste, smell, sight, and hearing.
- Balance is now also considered a sense.
- Touch is a complex sense that detects pressure, pain, hot and cold.
- The chapter focuses on touch, taste, smell, sight, and hearing.
- Senses are based on receptor cells or groups of receptors that form a sense organ.
- Receptor cells can be neuron endings or specialized cells in close contact with neurons.
- Receptors respond to stimuli like heat, light, pressure, and chemicals.
- Stimuli are forms of energy that receptors absorb and convert into electrical impulses.
- Neurons carry similar electrical impulses.
- Sight and hearing are distinguished by the part of the brain to which the neuron connects.
- The brain interprets impulses from the sense organ.
- Sensations occur in the brain.
Touch
- The skin contains receptors for pain, touch, and temperature.
- The concentration of these receptors varies in different locations around the body.
- There are few touch receptors in the heel of the foot.
- There are many temperature receptors at the elbow
- The elbow is often used for testing the temperature of a baby's bath.
