  • General sensations which include touch, pain, temperature, proprioception, and pressure.
  • Special Senses: Vision, hearing, taste, and smell which convey sensations to the brain through cranial nerves.

What are the 3 types of sensation?

  • Exteroceptive sensation (also termed superficial sensation): receptors in skin and mucous membranes.
  • Proprioceptive sensation (also termed deep sensation): receptors located in muscles, tendons, ligaments and joints.

What are the different types of sensations?

Broadly, these sensations can classify into two categories. First, general sensations which include

touch, pain, temperature, proprioception, and pressure

. Vision, hearing, taste, and smell are special senses which convey sensations to the brain through cranial nerves.

What is general sensation?

The general senses are

pain, temperature, touch, pressure, vibration, and proprioception

. Receptors for those sensations are distributed throughout the body. A sensory receptor is a specialized cell that, when stimulated, sends a sensation to the CNS.

What are the four basic sensations?

The thousands of nerve endings in the skin respond to four basic sensations —

pressure, hot, cold, and pain

— but only the sensation of pressure has its own specialized receptors. Other sensations are created by a combination of the other four.

What is a sensation test?

The sensory exam

involves evaluation of pain (or temperature), light touch, position sense, vibration, and discriminative sensations

. This portion of the exam is very subjective, and may become unreliable if repeated in quick succession. Therefore, your exam should not be rushed, but must proceed efficiently.

What are the primary sensation?

primary sensation

that resulting immediately and directly from application of a stimulus

. referred sensation (reflex sensation) one felt elsewhere than at the site of application of a stimulus.

How do I check my fine touch?

Sensory system testing involves provoking sensations of fine touch, pain and temperature. Fine touch can be evaluated with

a monofilament test

, touching various dermatomes with a nylon monofilament to detect any subjective absence of touch perception.

What 5 Sensations do the general senses detect?

Humans have five basic senses:

touch, sight, hearing, smell and taste

. The sensing organs associated with each sense send information to the brain to help us understand and perceive the world around us.

Which is a general sense organ?

The sense organs —

eyes, ears, tongue, skin, and nose

— help to protect the body. The human sense organs contain receptors that relay information through sensory neurons to the appropriate places within the nervous system.

What are special sensations?

The

sensory neurophysiology of our perception of sight, hearing, balance, taste, smell

are called special senses. In reality, all the general sensory receptor functions (touch, pressure, temperature) are special in their own way.

What are the 11 senses?

Human external sensation is based on the sensory organs of the eyes, ears, skin, vestibular system, nose, and mouth, which contribute, respectively, to the sensory perceptions of vision,

hearing, touch, spatial orientation, smell, and taste

.

What is sensation & perception?


Sensation occurs when sensory receptors detect sensory stimuli

. Perception involves the organization, interpretation, and conscious experience of those sensations. … Sensory adaptation, selective attention, and signal detection theory can help explain what is perceived and what is not.

What four variations of touch exist?

There are four primary tactile mechanoreceptors in human skin:

Merkel’s disks, Meissner’s corpuscles, Ruffini endings, and Pacinian corpuscle

; two are located toward the surface of the skin and two are located deeper. A fifth type of mechanoreceptor, Krause end bulbs, are found only in specialized regions.

Why do we test sensation?

The primary purpose of a sensory examination is

to evaluate sensory integrity and to assess the distribution and characteristics of the sensory impairment

. We are testing for dysfunction but we are also testing for protective-sensations and safety mechanisms.

How do you test for sensation?

For the ability to sense a sharp object, the best screening test uses

a safety pin or other sharp object to lightly prick the face, torso, and 4 limbs

; the patient is asked whether the pinprick feels the same on both sides and whether the sensation is dull or sharp.
