The spinal curves that assist in allowing a child to walk and run are the cervical, thoracic, lumbar, and sacral curves. These curves help maintain balance and support the body's weight, enabling upright posture and locomotion. The development of these curves is crucial as they provide stability and flexibility, facilitating movements such as walking and running as the child grows.
There are four curves in the spine. They are the Cervical, Thoracic, Lumbar and Pelvic curves.
Thoracic and sacral curves are present at birth also known as primary curves
A spinal curve refers to the natural or abnormal curvature of the spine. The spine typically has four natural curves: cervical, thoracic, lumbar, and sacral, which help with balance and movement. Abnormal spinal curves, such as scoliosis, kyphosis, or lordosis, can lead to discomfort, pain, and potential mobility issues. Proper alignment and curvature are essential for overall spinal health and function.
The large bundle of nerves extending from the brain through the spinal column is called the spinal cord. It is responsible for transmitting messages between the brain and the rest of the body, allowing for movement, sensation, and other bodily functions.
The nerves connected to the spinal cord are called spinal nerves.
The thoracic and sacral curves are the primary curves, as they are obvious at birth. The cervical and lumbar curves are secondary as they are modifications on the foetal position.
The opening for spinal cord and brain attachment is called the foramen magnum. This large opening is located at the base of the skull and connects the brainstem to the spinal cord, allowing for the passage of neural signals between the two. It plays a crucial role in the central nervous system's overall function.
Inflammation of the spinal cord is called Myelitis.
The spinal column features primary and secondary curves that each serve distinct functions. Primary curves, which include the thoracic and sacral curves, are present at birth and accommodate the shape of the fetal spine, providing space for internal organs. In contrast, secondary curves, such as the cervical and lumbar curves, develop later in life as a result of weight-bearing activities and upright posture, enhancing balance and support. Together, these curves contribute to the overall stability and flexibility of the spine.
Spinal nerves exit the vertebral column through small openings called intervertebral foramina. Once they have exited, these nerves carry sensory information from the body to the spinal cord and transmit motor signals from the spinal cord to the muscles, allowing for movement and sensation.
The primary curve was formed before birth but the secondary curve was formed after birth. Thats basically the difference between the two. hope that helps
In spinal extension, the primary agonists are the erector spinae muscles, which include the iliocostalis, longissimus, and spinalis muscle groups. These muscles contract to extend the vertebral column, allowing for movements such as arching the back or standing upright. Other supporting muscles, like the multifidus and semispinalis, also assist in this action.
