The occipital lobes are the center of our visual perception system. They are not particularly vulnerable to injury because of their location at the back of the brain, although any significant trauma to the brain could produce subtle changes to our visual-perceptual system, such as visual field defects and scotomas.
Definition of OCCIPITAL. : of, relating to, or located within or near the occiput or the occipital bone.— occipital noun. — oc·cip·i·tal·ly adverb. See occipital defined for kids. Scalp reconstruction is a surgical procedure for people with scalp defects. Scalp defects may be partial or full thickness and can be congenital or acquired. Because not all layers of the scalp are elastic and the scalp has a convex shape, the use of primary closure is limited. Occipital-parietal. The upper, back part of the head and skull. Occipital region. The back part of the head. Of course, the issue is much like that of witnesses who said the large defect was in the back of the head. Back can mean occipital bone, or it can mean the top of the head toward the back. Back can mean posterior, in other words Encephalocele, sometimes known by the Latin name cranium bifidum, is a neural tube defect characterized by sac-like protrusions of the brain and the membranes that cover it through openings in the skull.ncephaloceles of the back of the head are more common in Europe and North America, while encephaloceles on the front of the head more frequently occur in Southeast Asia, Africa, Malaysia, and Russia. Ethnic, genetic, and environmental factors, as well as parental age, can all affect the likelihood of encephaloceles. The occipital lobes are the center of our visual perception system.

Noun. 1. defect-an imperfection in a bodily system; visual defects; this device permits detection of defects in the lungs. myelatelia-any developmental defect of the spinal cord. imperfection, imperfectness-the state or an instance of being imperfect. Encephalocele is a rare type of neural tube defect (NTD) present at birth that affects the brain. The neural tube is a narrow channel that folds and closes during the third and fouth weeks of pregnancy to form the brain and spinal cord. Location and Function of the Occipital Lobe. The occipital lobe is located in the posterior, or back, region of the cerebrum, superior to, or above, the cerebellum. It's protected by cranial bones, with the primary protective bone being the occipital bone. When located in the back of the skull, encephalocele often is linked to nervous system problems. Encephalocele usually is seen with other brain and face defects. Signs of encephalocele can include: 1  Buildup of too much fluid in the brain. 2  Complete loss of strength in the arms and legs.ncephalocele is a rare type of neural tube defect (NTD) present at birth that affects the brain. The neural tube is a narrow channel that folds and closes during the third and fouth weeks of pregnancy to form the brain and spinal cord. These defects are caused by failure of the neural tube to close completely during fetal development. Encephaloceles cause a groove down the middle of the skull, or between the forehead and nose, or on the back side of the skull. The severity of encephalocele varies, depending on its location.ncephaloceles of the back of the head are more common in Europe and North America, while encephaloceles on the front of the head more frequently occur in Southeast Asia, Africa, Malaysia, and Russia. Ethnic, genetic, and environmental factors, as well as parental age, can all affect the likelihood of encephaloceles.
