GENERAL HISTOLOGY

Detailed explanation-1: -The foramen magnum functions as a passage of the central nervous system through the skull connecting the brain with the spinal cord. On either side of the foramen magnum is an occipital condyle . These condyles form joints with the first cervical vertebra.

Detailed explanation-2: -Apart from the spinal cord, its associated meninges and cerebrospinal fluid, the foramen magnum also transmits the vertebral arteries, the anterior and posterior spinal arteries, dural veins and the spinal roots of the accessory nerve (CN XI).

Detailed explanation-3: -The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine. Ligaments and muscles help keep the vertebrae in the right position.

Detailed explanation-4: -Your spinal cord carries nerve signals from your brain to your body and vice versa. These nerve signals help you feel sensations and move your body. Any damage to your spinal cord can affect your movement or function.
