The shape of the calcium channel protein allows only calcium ions to pass through the channel. ... There the calcium ions interact with the neurotransmitter containing vesicles (membrane-bound containers) causing them to fuse with the cell membrane, and release the neurotransmitters into the synaptic cleft. Calcium (Ca2+) is a vital element in the process of neurotransmitter release; when Ca2+ channels are blocked, neurotransmitter release is inhibited. Storage of the neurotransmitter in storage granules or vesicles in the axon terminal. Calcium enters the axon terminal during an action potential, causing release of the neurotransmitter into the synaptic cleft. After its release, the transmitter binds to and activates a receptor in the postsynaptic membrane.

Polyunsaturated fats can help lower your LDL (bad) cholesterol. Cholesterol is a soft, waxy substance that can cause clogged or blocked arteries (blood vessels). Having low LDL cholesterol reduces your risk for heart disease.

Polyunsaturated fats include omega-3 and omega-6 fats. These are essential fatty acids that the body needs for brain function and cell growth. Our bodies DO NOT make essential fatty acids, so you can only get them from food.

Omega-3 fatty acids are good for your heart in several ways. They help:

  • Reduce triglycerides, a type of fat in your blood
  • Reduce the risk of developing an irregulat heartbeat (arrhythmia).
  • Slow the buildup of plaque in your arteries
  • Slightly lower your blood pressure

It is thin, fibrous, flexible connective tissue, which is mainly found in the external ear, larynx, respiratory tract, and the articulating surface of the joints. These cartilages lack blood vessels, therefore the growth and development of these tissues are slower compared to the other tissues. Altogether there are three different types of cartilages and it includes:

  1. Hyaline cartilage: It serves as a shock absorber and allows the smooth movement of the bones at joints. They are mainly found in the nose, respiratory tract, and joints
  2. Fibrocartilage is found in the knee, and it is tough and inflexible.
  3. Elastic cartilage is found in-ear, epiglottis, and larynx. It is the most flexible cartilage.
