Flashcards in Lab 11: Human Sensory Systems Deck (25)
The human sensory system is comprised of two types of senses:
Somatic and special
__________ are specialized cells, or clusters of cells, that send information via afferent pathways to the brain.
Five basic types of sensory receptors:
Mechanoreceptors, chemoreceptors, electromagnetic receptors, thermoreceptors, and pain receptors
Mechanoreceptors detect mechanical energy such as:
Pressure, touch, and sound
Human __________ contains large numbers of mechanoreceptors.
Chemoreceptors detect changes in chemical concentrations such as:
Smell and taste
Changes in __________ such as blood glucose levels are also detected by chemoreceptors.
Electromagnetic receptors detect electromagnetic energy such as:
Light and electricity
__________ contains electromagnetic receptors.
Heat and cold
Thermoreceptors located in the __________ detect changes in core body temperature and maintain thermoregulation.
Pain receptors are free nerve endings that detect:
Pain receptors are located both in:
The skin and within certain internal organs
All receptors perform the __________ function.
Somatic senses are associated with:
Skin, muscle, viscera, and joints
Somatic senses are comprised of:
Mechanoreceptors, thermoreceptors, and pain receptors
Special senses are a product of:
The special senses are comprised of:
Electromagnetic sensors, chemoreceptors, and mechanoreceptors
Some receptors become less __________ if stimulus is constantly present.
Some receptors become less sensitive if stimulus is constantly present. These types of receptors are __________.
The decreased responsiveness of the receptors is called:
Receptors that either do not adapt to continuous stimulation or adapt very slowly are:
__________ __________ are generally tonic in nature.
Occur throughout the epidermis and are sensitive to light touch.
