Answer:
Pericardial sac has protective tole
Explanation:
Pericardial sac or pericardium is a fibrous tissue that surrounds the heart. It has two coats:
- the outter coat-parietal pericardium
- the inner coat-visceral pericardium or epicardium which is double-layered and contains pericardial fluid between those two layers (pericardial fluid is necessary as a lubricant for the heart movement).
Besides lubrication, percardium also protects heart from infections, fixes it and limits its movements.

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing "an influx of Cl-".
<u>Explanation:</u>
The neurotransmitters which have inhibitory influence on the neuron are termed as "Inhibitory neurotransmitters". The major inhibitory neurotransmitters involve serotonin and gamma-aminobutyric acid (GABA) in the brain and brain stem (spinal cord) respectively.
GABA uptake is temperature and ion-dependent as require both 
and 
. Even glycine transporters are also members of the large family of 
dependent neurotransmitter transporters. Both of them with the GABA transporters share approximately 50% sequence identity.
