Lab 2 Flashcards
1
Q
What channnel does the pulse traducer plug into the iWork TA box?
A
A5
2
Q
Simple nervous reflex arc
A
- Receptor that identifies the stimulus
- Afferent neuron carries sensory info to integration center
- Efferent neuron transmits motor info to an effector cell
- Effector cells goves response to initial stimulus
3
Q
What is the integration center for spinal reflexes?
A
spinal cord
4
Q
monosynaptic?
A
only involves two neurons and afferent neuron that synapses with effector neuron in spinal cord
5
Q
stroop effect
A
- impact of a stimulus interference with the task being performed, it impacts completing the task effectively
6
Q
What reflex arc is shorter according to our lab?
A
auditory relex arc
7
Q
What had the shortest reaction time?
- simple
- prompted
- predictble
A
- predicatble
8
Q
Patellar stretch is
A
Ipsilateral
9
Q
Ipsilateral
A
- response is on same side of the body
10
Q
Corneal reflex response is
A
- response is bilateral
11
Q
Cilispinal reflex
A
Ipsilateral
- when right side of neck is stimulated y
12
Q
Patellar stretch reflex is what kind of synapse?
A
monosynaptic
13
Q
Reciprocal inhibition
A
multisynaptic
14
Q
What neuron controls the motor cortex?
A
Upper motor nueron
15
Q
What neuron controls the alpha neurom
A
Lower motor neuron
16
Q
What neuron controls the gamma motor neuorn
A
Lower motor neuron
17
Q
What happens when the alpha nuerons are damaged?
A
Flaccid paralysis, when alpha nuerons are damaged they cannot be stimulated and lose tone
18
Q
What happens if the motor cortex is damaged?
A
Spastic paralysis would happen. the muscles under the control of motor neurons couldn’t function and perform movement directed by cerebral motor cortex
19
Q
How else can somatic reflex arcs be categorized
A
- ipsilateral
- contralateral
- consensual
- bilateral
20
Q
What do alpha motor neurons do?
A
they stimulate the extrafusal fibers of the skeletal muscle
21
Q
biceps brachii tendon reflex
A
- biceps brachii contract and triceps are inhibited (antagonists)
- ipsilateral
22
Q
Patellar reflex
A
- quadriceps femoris msucle are contracted and biceps femoris muscles were inhibited and they are ipsilateral
23
Q
Achilles tendon reflex
A
- Gastrochemus muscle was stimulated and thats what made my toes contract
- msucles that are responsible for dorsiflexion were inhibited
- ipsilateral
24
Q
Plantar reflex and babinski sign- normal
A
- adduction and plantar of the toes

73
Has occurred when you are no longer aware of your clothes touching your skin
adaptation
74

afterimage
76
occurs when visceral pain is felt as cutaneous pain
reffered pain
77
area of tissue containing the receptors of one sensory neuron
receptor field
78
second- oreder neuron crosses from one side of the CNS to the other
dessucation
79
receptors that detect changes in the internal environment
interoreceptors
80
Which are had the greatest ability of to detect two points
index finger tip
81
Least abiltiy to detect to point
neck
82
Why is there a difference in distribution and overlap of receptors you observed in the two point discrimination
Two points are felt as the same if they are within the same receptor field.
83
Explain the role adaptation plays in perception afterimage
phasic receptors adapt quickly and may keep sending AP, even when removed and this is an afterimage

97
As individual focusses on an object that is getting closer is
```
1. 4- c
