GENERAL HISTOLOGY

Detailed explanation-1: -The spinal cord is about 18 inches (45 centimeters) in length and is relatively cylindrical in shape. The cervical (neck) and lumbar (lower back) segments house the spinal cord’s two areas of enlargement. A fibrous band called the filum terminale begins at the tip of the conus medullaris and extends to the pelvis.

Detailed explanation-2: -The spinal cord measures roughly 45 cm in the adult male and 42 cm in the adult female. [1] It is a downward extension of the medulla oblongata after it passes through the foramen magnum.

Detailed explanation-3: -Femur or thigh bone is the largest bone in human body. Spinal cord is not considered as largest bone because it is not a single bone, instead it is composed of 33 small separate bones interlocked together.

Detailed explanation-4: -Relative Length of Spinal Cord Neuronal Segments The longest spinal cord neuronal segments were found in the thoracic spinal cord, and each segment constituted approximately 5% of the whole spinal cord.
