Pain, pressure, temperature, proprioception, two-point discrimination, vibration, olfactory, vision and visceral sensations are all examples of sensory m---------.
1 of 19
Free nerve endings
Unspecialised, afferent nerve fibre ending of a sensory neuron used to detect pain
2 of 19
Muscle spindles
Sensory receptors within the body of a muscle that primarily detect changes in the length of the muscle
3 of 19
Baroreceptors
Receptors that sense pressure changes by responding to change in the tension of the arterial wall
4 of 19
Chemoreceptors
Receptors that detect changes in blood oxygen, carbon dioxide and pH
5 of 19
Retina
Receives light that the lens has focused, converts the light into neural signals, and sends these signals on to the brain for visual recognition
6 of 19
Hair cell of the ear
Sensory receptors of both the auditory system and the vestibular system
7 of 19
Vestibular apparatus
Receives sensory information about motion, equilibrium and spatial orientation
8 of 19
Dorsal column
The sensory/ascending tract that transmits fine touch, pressure and proprioception
9 of 19
Dorsal root ganglion
Where are the first order neurones of the dorsal column, spinothalamic and spinocerebellar tracts located?
10 of 19
Medulla oblongata
Where are the second order neurons of the dorsal column tract (found in the dorsal column nuclei) located?
11 of 19
Decussation
What happens in the brainstem of the dorsal column tract,
12 of 19
Medial leminiscus
What is the name of the white matter tract from which the axons of the dorsal column tract and spinocerebellar tract ascend?
13 of 19
Thalamus
Where are the third order neurons of the dorsal column tract and the spinothalamic tract located?
14 of 19
Spinothalamic
The sensory/ascending tract that transmits information about crude touch (anterior) and about pain and temperature (lateral)
15 of 19
Posterior horn
Where are the second order neurons of the spinothalamic tract located?
16 of 19
Spinocerebellar
The sensory/ascending tract that transmits information about touch and proprioception
17 of 19
Ipsilateral cerebellum
Where the third order neurons of the spinocerebellar tract are located and the axons terminate
18 of 19
Lateral corticospinal
The motor/descending tract for voluntary movement, i.e. for moving your hands
