Study Notes
General and Special Sensory Receptors
- General sensory receptors detect touch, pressure, temperature, pain, stretch, and vibration.
- Special sensory receptors identify vision, hearing, equilibrium, smell, and taste.
Nociceptors
- Nociceptors function as pain receptors, distributed throughout the body but absent in the brain.
Root Hair Plexus
- Comprised of free nerve endings that wrap around hair roots to sense hair movements or distortions.
Proprioception
- Proprioception gathers sensory input from mechanoreceptors about body position and limb movement, crucial for coordination.
Nasal Cavity
- Serves as the interior portion of the nose, playing a vital role in olfactory perception.
Oral Cavity
- Housing key structures like lips, palates, salivary glands, tongue, teeth, and periodontium, it is essential for digestion and taste.
Tongue
- Functions in manipulating food for chewing and swallowing while also serving as a primary taste organ.
Optic Nerve
- Transmits neural impulses from the retina in the eye to the brain, essential for vision processing.
Five Tastes
- The primary taste categories are Sweet, Sour, Bitter, Umami, and Salty, contributing to flavor perception.
Types of Receptors
- Includes five main receptor types:
- Mechanoreceptors (respond to mechanical stimuli)
- Thermoreceptors (detect temperature changes)
- Proprioceptors (monitor body position)
- Pain receptors (nociceptors)
- Chemoreceptors (sense chemical stimuli).
Pain Receptors
- Consist of nociceptors reacting to intense chemical, mechanical, or thermal stimuli. They are categorized into three types:
- Cutaneous (skin)
- Somatic (joints & bones)
- Visceral (body organs).
Referred Pain
- Describes the phenomenon where pain is perceived in a location other than its actual source.
Adaptation vs. Projection
- Projected Pain is incorrectly localized due to the ascending pain pathway.
- Pain Adaptation occurs when the body develops a tolerance to consistent pain stimuli over time.
Special Senses vs. General Senses
- Special senses have more complex structures, localized in specific organs, including smell (olfaction), taste (gustation), balance (equilibrium), hearing, and vision.
- General senses are widely distributed throughout the body and include sensations such as temperature, pain, touch, pressure, vibration, and proprioception.
