Nationality has nothing to do with pineal glands but heredity might.
There are many glands that make up the endocrine glands. These glands include the pancreas, the thymus gland, the pituitary gland, the pineal glands, and the adrenal glands.
Endocrine
They are called glands and they make up the endocrine system. Some glands are the hypothalamus, the pituitary gland, the thyroid and parathyroids, the adrenal glands, the pineal body and the ovaries and testes.
Endocrine glands, which are special groups of cells, make hormones. The major endocrine glands are the pituitary, pineal, thymus, thyroid, adrenal glands and pancreas. In addition, men produce hormones in their testes and women produce them in their ovaries.
The endocrine system is made up of glands that make and secrete hormones. These include hormones that are responsible for a bodies metabolism, regulating growth and sexual development and function . The endocrine system is made up of numerous glands. The major glands are the hypothalamus, thyroid, parathyroid, pineal body, adrenals and pituitary. Reproductive organs are also part of the system - ovaries or testes.
The pineal gland can be activated by many sounds, even an A natural 432 Hertz frequency!
Hormones are produced/secreted from endocrine glands in the body, the endocrine glands in the body include; adrenal glands, thyroid glands, parathyroid glands, the pancreas, testis, ovaries, pineal gland and the pituitary gland situated under the hypothalamus. Hormones are chemical messages which bring about a broad series of long lasting changes. Neurons are an electro chemical message which reacts from a stimulus, they make up the nervous system. neurons are a much faster message then hormones (milli seconds) which does not persist, whilst hormones are a slower message that persists. Neurons can target individual cells whilst hormones can only target cells with the right receptor, whole organs or even systems.

If limited to only two things, I would say the pituitary and adrenal glands, but the thalamus, heart, hypothalamus, pancreas, kidneys, pineal gland and sex organs are also important contributors to the endocrine system.
Yes, there is a difference between the bulbourethral glands and the vas deferens. The bulbourethral glands are responsible for secreting a clear fluid that helps lubricate the urethra during sexual arousal, while the vas deferens is a tube that carries sperm from the testicles to the urethra during ejaculation.
Sebaceous glands, also known as oil glands.
