Nervous Physiology

Question 1


1.1 Declarative memory (2)

Declarative memory means memory of the various details of an integrated thought, such as

memory of an important experience that includes


Memory of the surroundings


Memory of time relationships


Memory of causes of the experience


Memory of the meaning of the experience


Memory of one’s deductions that were left in the person’s mind

1.2 Habituation (2)

Habituation stands for a kind of negative memory: the brain has the capability to learn to ignore

information that is of no consequence. It results from inhibition of the synaptic pathways.

1.3 Reflexive learning (2)

This is a type of learning that depends on physically repeating the required tasks over and over

again, rather than on symbolical rehearsing in the mind.

1.4 Strabismus (2)

Strabismus means lack of fusion of the eyes in one or more of the visual coordinates: horizontal,

vertical or rotational. This is caused by abnormal “set” of the fusion mechanism of the visual


1.5 Sensorineural deafness (2)

“Nerve deafness”: it is caused by the impairment of the cochlea or auditory nerve. If the cochlea

orauditory nerve is destroyed, it causes permanent deafness.

1.6 Interneuron (2)

Interneturons are nerve cells and are present in all areas of the cord gray matter. They are about

30 times as numerous as the anterior motor neurons. They are small and highly excitable, often

exhibiting spontaneous activity. They have many interconnections with one another.

1.7 Dysmetria (2)

Dysmetria is a form of cerebellar disease. In the absence of the cerebellum, the subconscious

motor control system cannot predict how far movements will go. Therefor movements ofte n

overshoot their intended mark, and the conscious portion of the brain overcompensates in the

opposite direction for the succeeding compensatory movement.

1.8 Amnesia (2)

Amnesia means the inability to remember. We distinguish between...
