  • Motor Functions – directs your body’s voluntary muscle movements.
  • Sensory Functions – monitors sensation of touch, pressure, temperature and pain.
  • Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).

    What are the 5 sections of the spinal cord?

    The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

    How many parts does the spinal cord have?

    The spine is divided into 33 segments, 24 of which are mobile. Working from the top downwards, the cervical spine is the portion of the spine within the neck, and consists of 7 vertebrae (C1 to C7).

    What is the structure of the spinal cord?

    What is Spinal Cord, Parts of Spinal Cord with Pictures. Extending right from the medulla oblongata and running through vertebral column in your body, it resembles a long, thin, tubular structure that is composed of nervous tissue and the accessory cells.

    Is the spinal cord under the influence of the brain?

    A huge part of spinal cord function is under the influence of the brain, as it functions to relay information to and from the periphery. But there are many reflexes that are generated in the spinal cord independently from the brain. Spinal reflexes are either monosynaptic or polysynaptic.

    Where does the spinal cord run through the skull?

    The Spinal cord runs through a hollow case from the skull enclosed within the vertebral column. Spinal nerves arise from different regions of the vertebral column and are named accordingly, the regions are – Neck, chest, pelvic and abdominal. Cross-section of spinal cord displays grey matter shaped like a butterfly surrounded by a white matter.

    Which is part of the spinal cord fuses together?

    The lower most portion of the neural tube that gives rise to one pair of coccygeal nerves and leaves the vertebrae through sacral hiatus. However, here you will find that three segments of the region fuse together to form a single unit.

    What is the spinal cord’s main job?

    The spinal cord is the main route for information to be transported to the brain from the peripheral nervous system . Together with the brain, the spinal cord composes the central nervous system . The cord resides within a tunnel of bones called vertebrae. The vertebrae help protect this vital part of the human anatomy.

    What are the three areas of the spinal cord?

    The spinal cord is divided into four major parts: the cervical, thoracic, lumbar, and sacral nerves. Collectively, the entire spinal cord is divided into 31 segments; at every segment, there is a pair of right and left spinal nerves.

    What is the inner portion of the spinal cord?

    The spinal cord is contained in the center cavity of the vertebral column (back bone) which protects the spinal cord from injury. It has an inner mass of gray matter and an outer covering of white matter. It carries messages that coordinate movement and sensation.
