Senses You Didn’t Know You Have | SciShow Kids

This episode explores how humans perceive the world, examining our senses beyond the traditional five.
There are three key takeaways from this discussion. First, human perception extends well beyond the traditional five senses. Second, proprioception, or body awareness, is a fundamental sense for controlled movement. Finally, all senses operate through specialized receptors that convert external information into brain signals.
Crucial abilities like balance, temperature detection, and pain perception are also vital sensory functions. These less commonly acknowledged senses are critical for safety and navigating our environment effectively.
Proprioception allows individuals to understand their body's position in space without visual confirmation. This enables complex physical actions and coordination, forming the basis for motor control.
All senses rely on specialized receptors within sensory organs to gather information from the environment. These receptors convert external stimuli, such as light or sound, into neural signals. These signals are then transmitted to the brain for interpretation, forming our sensory experience.
This discussion highlights the remarkable complexity and breadth of human sensory perception.
Episode Overview
- The episode begins with the host, Jessie, and her robot mouse friend, Squeeks, discussing the five senses as Squeeks prepares for a trip around the world.
- Two duck puppets, Bill and Web, call in to settle an argument about whether there are only five senses or if there are more.
- Jessie explains that while the five traditional senses are well-known, humans actually have several other important senses, such as the sense of balance and body awareness.
- The episode breaks down how senses work through specialized receptors that send signals to the brain, using examples like photoreceptors for sight and pain receptors for safety.
Key Concepts
- The five traditional senses are sight, hearing, touch, taste, and smell.
- Senses rely on sensory organs and specialized parts called receptors to gather information from the environment.
- Receptors convert external information (like light or sound) into signals that are sent to the brain for interpretation.
- Humans have senses beyond the traditional five, including the sense of temperature, pressure, pain, and balance.
- Proprioception is the sense of body awareness, which allows you to know where your body parts are in space without looking at them.
Quotes
- At 01:14 - "I say there are five senses: Sight, Hearing, Touch, Taste, and Smell." - Bill the duck states his side of the argument, representing the common belief about the number of human senses.
- At 04:44 - "Proprioception is the sense of where our body is in space." - Jessie explains the meaning of proprioception, a less commonly known but vital sense.
Takeaways
- Our bodies have more than just the five traditional senses of sight, sound, smell, taste, and touch.
- Senses like balance, temperature, and pain are also critical for navigating the world and staying safe.
- Proprioception, or body awareness, is a key sense that helps us control our movements and understand our body's position without needing to see it.
- All senses work through a process where receptors gather information and send signals to the brain to be processed.
