A more thorough explanation:

A Member of Parliament (MP) is a person who has the right to sit in one of the two houses of Parliament. They are elected by the people to represent their constituency and make decisions on their behalf.

For example, in the United Kingdom, there are 650 Members of Parliament who sit in the House of Commons. Each MP represents a different area of the country and is responsible for listening to the concerns of their constituents and bringing them to the attention of the government.

A membership committee is a group of people who are responsible for managing the membership of an organization. They may be in charge of reviewing applications, approving new members, and maintaining membership records.

For example, a sports club may have a membership committee that is responsible for ensuring that all members have paid their dues and are following the club's rules and regulations. The committee may also be responsible for organizing events and activities for members.

Membrana is a Latin word that means "parchment". In history, it was used to refer to a skin of parchment or a notebook made of leaves of parchment.

For example, in medieval times, important documents such as royal charters and legal agreements were often written on parchment. These documents were referred to as membrana and were considered to be very valuable and important.
