Sensory Reception Flashcards

Flashcards covering key vocabulary and concepts from the Sensory Reception lecture notes.

Sensory Reception Steps

The four steps of sensory stimulus: 1) reception 2) transduction 3) transmission 4) perception

Modality

Type of sensory stimulus.

Chemoreceptors

Respond to chemicals; involved in olfaction (smell) and gustation (taste).

Olfaction

Sense of smell; detection of chemicals in the air.

Gustation

Sense of taste; detection of ingested chemicals.

Mechanoreceptors

Respond to movement; involved in touch/pressure, baroreceptors, proprioception, and equilibrium.

Cochlea

Inner ear structure where transduction of sound occurs.

Vestibular Apparatus

Responsible for orientation, acceleration, and rotation.

Rods

Sensitive to dim light, not color.

Cones

Detect color.

Rhodopsin

Changes shape conformation for light.

Nociceptors

Register painful stimuli; can be polymodal (respond to temperature, pressure, chemicals).

Electroreceptors

Detect electric fields.

Olfactory Bulb

Part of the brain where olfactory signals are processed and interpreted.

Statocysts

Detect pressure changes in water.

Transduction

Conversion of a signal to the control center.

Transmission

Sending a signal to an effector.

Vomeronasal Organ

Detects airborne odorants and pheromones.

Ampullae of Lorenzi

Detect electrical fields in water

Lateral Line

A system of sensory organs found in aquatic animals that detects water movements and vibrations using hair cells.

Basilar Membrane

A structure in the cochlea of the inner ear that vibrates in different locations in response to different frequencies of sound

Vomeronasal Organ

A chemoreceptor structure located in the nasal cavity of many vertebrates that detects pheromones and other chemical signals.

Osmmatidium

A sensory unit found in the compound eyes of insects, responsible for detecting light and forming images.
