Reorder the following steps in sensory reception sensation begin

• A sensation begins when a receptor detects a stimulus

• if the stimulus is strong enough, the receptor causes a sensory neuron to send an impulse to the brain and spinal cord

• When the impulse arrives at the brain we may experience a sensation such as a sight or sound

Match the following three types of information transmitted by sensory receptors

• type

• cold receptors respond only to cold while light receptors respond only to light.

• location

• uses sensory projection to know in the brain where the stimulus originated (receptive field)

• intensity

• the stronger a particular stimulus, the more nerve fibers fire.

react to various chemicals, including odors and tastes. as well as the concentration of various chemicals in t he body (such as glucose or carbon dioxide)

• mechanoreceptors

• thermoreceptors

• nociceptors

• chemoreceptors

receptors are activated by a change in temperature

• mechanoreceptors

• chemoreceptors

• thermoreceptors

• nociceptors

These receptors respond to factors that change the position of a receptor, such as pressure, stretch, or vibration.

• photoreceptors

• chemoreceptors

• mechanoreceptors

• thermoreceptors

Pain receptors that respond to tissue damage from trauma, heat, chemicals, pressure, or a lack of oxygen

• nociceptors

• thermoreceptors

• mechanoreceptors

• chemoreceptors

found only in the eyes, these receptors respond to light

• photoreceptors

• nociceptors

• thermoreceptors

• mechanoreceptors

When a stimulus is continuous, the firing frequency of the nerve begins to slow, causing the sensation to diminish

• adaptation

• intensity

• projection

• proprioceptor

specialized receptor found in skeletal muscle, joints, and tendons, and provide information about body movement, muscle stretch, and general orientation of the body

• proprioceptor

• adaptation

• mechanoreceptor

• nociceptor

General senses are pain, pressure, touch, stretch, and temperature

• true

• false
