Study Notes
Sensory Receptors and the Brain
- Stimulating sensory receptors initiates the process of sensation, where the receptors convert external stimuli into electrical signals.
- These electrical signals, or action potentials, travel along the sensory neurons to the brain.
- When action potentials reach the cerebral cortex, the brain interprets the signals, resulting in perception, awareness, and understanding of the environment and the body.
Means of Information Gathering
- The brain receives information about the environment and the body through sensory receptors, which are specialized to detect specific types of stimuli, such as light, sound, touch, taste, and smell.
Simple Structure and Physiology
- Sensory receptors are relatively simple in structure and physiology, with a single function of detecting specific stimuli.
Characteristics of Free Nerve Endings
- Free nerve endings, a type of sensory dendrite, lack a connective tissue sheath, allowing them to directly respond to stimuli.
