The urinary bladder wall is composed of four main layers:

1. Mucosa: This is the innermost layer of the urinary bladder. It is made up of transitional epithelium cells and connective tissue.

2. Submucosa: This layer lies just outside the mucosa. It is composed of connective tissue and helps support the mucosa.

3. Muscularis: This layer is also known as the detrusor muscle. It is responsible for the contraction of the bladder during urination.

4. Adventitia: This is the outermost layer of the urinary bladder. It is composed of connective tissue and helps to protect the bladder.

So, the correct answers are: mucosa, submucosa, muscularis, and adventitia.
