Study Notes
- Sensory system study guide
Synesthesia
- Stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway.
General Senses
- Receptors are found throughout the body, including joints and organs.
Special Senses
- Specialized receptors are found in the head, specifically in the eyes, ears, and mouth.
Sensation
- It is the feeling that occurs when the brain interprets a sensory nerve impulse.
Projection
- It is the process where the brain causes a feeling to stem from a specific source.
Sensory Adaptation
- Sensory receptors stop sending signals when they are repeatedly stimulated.
Peripheral Nervous System
- Receptor cells in this system are activated by stimuli in the environment.
Receptor Cell Classification
- Receptor cells can be classified based on cell type, position, and function.
Free Nerve Endings
- These are dendrites embedded in tissue that act as receivers, responding to pain and temperature.
Encapsulated Receptors
- They are embedded in connective tissue to increase sensitivity to pressure and touch.
Specialized Receptors
- These are located in the retina of the eye.
Exteroreceptor
- Located near the external environment, such as in the skin.
Interoreceptor
- Interprets stimuli from internal organs.
Proprioreceptor
- Located near moving body parts, interprets position.
Chemoreceptor
- Detects chemicals, mostly found in the nose and mouth.
Osmoreceptor
- Responds to solutes in body fluids.
Thermoreceptor
- Detects temperature changes.
Mechanoreceptor
- Responds to pressure, vibration, and body position.
Nocireceptor
- Detects pain, specifically from chemicals released when tissue is damaged.
Visceral Pain
- Occurs in visceral tissues such as the heart, lungs, and intestines.
Referred Pain
- It is felt as though it is coming from a different part of the body; for example, heart pain may be felt in the arm or shoulder.
Acute Pain
- Originates from the skin and usually stops when the stimulus stops, such as after a needle prick.
Chronic Pain
- A dull, aching sensation.
Universal Pain Assessment Tool
- Intended to help patients assess pain according to their individual needs.
FLACC
- Stands for face, legs, activity, cry, consolability, used for pain assessment.
Olfactory Pathway
- Odor molecule triggers olfactory receptor cell which triggers olfactory bulb which triggers olfactory tract which triggers the limbic system.
Papillae
- Taste buds
Five Types of Taste
- Sweet, sour, salty, bitter, and umami (savory).
Labyrinth
- Communicating chambers and tubes in the ear.
Semicircular Canals
- Responsible for the sense of equilibrium.
Cochlea
- Responsible for the sense of hearing.
Organ of Corti
- Contains hearing receptors; hair cells detect vibrations.
Steps in Hearing
- Sound waves enter the external auditory canal.
- The eardrum vibrates.
- Auditory ossicles (malleus, incus, stapes) amplify vibrations.
- The stapes hits the oval window, transmitting vibrations to the cochlea.
- Organs of Corti contain receptor cells (hair cells) that deform from vibrations.
- Impulses are sent to the vestibulocochlear nerve.
- The auditory cortex of the temporal lobe interprets sensory impulses.
- The round window dissipates vibrations within the cochlea.
Cochlear Implants
- Receive sound from the outside environment, process it, and send small electric currents near the auditory nerve.
Static Equilibrium
- Maintains stability and posture.
Cerebellum
- Interprets impulses from the semicircular canals and maintains overall balance.
Dynamic Equilibrium
- Balance during sudden movement.
Disorders of the Sensory System
- Synesthesia, anosmia, tinnitus, anhidrosis (inability to sweat), and congenital analgesia (mutations in genes prevent nerve impulses from pain receptors from sending signals to the brain).
Careers in Hearing
- Audiologist, speech-language pathologist, sign language interpreter, and teacher for the deaf and hearing impaired.
Special Senses
- Smell (olfactory organs), taste (taste buds), hearing & equilibrium (ears), and sight (eyes).
External Ear
- Includes the auricle (pinna), external auditory meatus, and auriculares muscles.
Middle Ear (Tympanic Cavity)
- Includes the eardrum and auditory ossicles (malleus, incus, stapes) that transmit and amplify vibrations.
- Also contains the auditory tube (Eustachian tube).
