Q

Sensory receptors in deeper somatic structures

A

Proprioceptors

1
Q

Sensory receptors in the skin, mediating superficial sensation

A

Exteroceptors

2
Q

Touch

A

Meissner corpuscles

3
Q

Pressure

A

Merkel discs

4
Q

Warmth & skin stretch

A

Ruffini plumes

5
Q

Cold

A

Krause end bulbs

6
Q

Vibration & tickle

A

Pacinian corpuscles

7
Q

Pain

A

Free nerve endings

8
Q

The sensation most commonly diminished with advancing age (especially at the toes & ankles)

A

Vibration

9
Q

Inability to recognize shape & form

A

Stereoanesthesia

10
Q

Inability to identify an object by palpation, even though the primary sense data are intact

A

Astereognosis

11
Q

A disturbance in which a one-sided lesion lying posterior to the post-central gyrus of the dominant parietal lobe results in an inability to recognize an object by touch in both hands

A

Tactile agnosia

12
Q

Symmetrical distal sensory loss
Sensory loss may affect one modality preferentially
Areflexia or hyporeflexia
Weakness, if present, symmetrical

A

Polyneuropathy

13
Q

Asymmetrical sensory & motor loss
Proximal & distal parts of limb differentially affected
Reflex loss limited to region of affected root(s)

A

Polyradiculopathy

14
Q

Implicates all sensory modalities
Proximal body parts affected
Ataxia

A

Ganglionopathy

15
Q

Prominent loss of position & vibration sense in feet
Romberg sign
Secondary (Charcot) joint deformities
Areflexia

A

Tabetic syndrome

16
Q

Loss of all sensory modalities below level of lesion

A

Complete transverse lesion of the SC/ complete spinal sensory syndrome

17
Q

Loss of pain sense opposite to the lesion & beginning several levels below it
Loss of vibration & joint position sense on the side of the lesion & below it

A

Hemicord/ Brown-Sequard

18
Q

Loss of pain & thermal sense with preservation of touch & position/vibration over restricted region of neck, cape, arms, & hands

A

Syringomyelia

19
Q

Same as tabetic syndrome but reflexes are preserved

A

Posterior column syndrome

20
Q

Loss of pain & temperature sensation below the level of the lesion with relative or absolute sparing of proprioceptive sensation; spastic paralysis is a prominent feature

A

Anterior myelopathy/ Anterior spinal artery syndrome
