An area in the occipital lobe, the visual processing center in the brain. The lingual gyrus extends to the temporal lobe of the brain. A stroke damaging the lingual gyrus reportedly can cause a loss of dreaming, suggesting that the lingual gyrus plays a key role in generating or recalling dreams. The lingual gyrus is so-named because it resembles the tongue in shape.
- Lining, uterine
The inner layer of the uterus (womb); the cells that line the womb; anatomically termed the endometrium. This tissue is normally shed monthly in response to the hormonal changes of the menstrual period.
The tendency for genes to be inherited together as a package because of their location near one another on the same chromosome.
- Linkage analysis
Study aimed at establishing linkage between genes. Today linkage analysis serves as a way of gene-hunting and genetic testing. Linkage is the tendency for genes and other genetic markers to be inherited together because of their location near one another on the same chromosome. A gene is a functional physical unit of heredity that can […]
- Linkage map
A map of the genes on a chromosome based on linkage analysis. A linkage map does not show the physical distances between genes but rather their relative positions, as determined by how often two gene loci are inherited together. The closer two genes are (the more tightly they are linked), the more often they will […]
- Lip, cleft
A fissure in the upper lip that is due to failure of the left and right sides of the fetal lip tissue to fuse, an event that should take place by 35 days of fetal age. Cleft lip can be on one side only or on both sides. Because failure of lip fusion can impair […]
