From Wikipedia:
The nuclear lamina is a dense (~30 to 100 nm thick) fibrillar network inside the nucleus of an eukaryotic cell. It is composed of intermediate filaments and membrane associated proteins. Besides providing mechanical support, the nuclear lamina regulates important cellular events such as DNA replication and cell division. Additionally, it participates in chromatin organization and it anchors the nuclear pore complexes embedded in the nuclear envelope.
The nuclear lamina is associated with the inner face of the bilayer nuclear envelope whereas the outer face stays continuous with the endoplasmic reticulum.

What is the structure and function of a lamina in a leaf?
The lamina, also known as the leaf blade, is the broad, flat part of a leaf. Its main function is to capture sunlight for photosynthesis, which is the process by which plants make their own food. The lamina is made up of cells that contain chloroplasts, where photosynthesis takes place. Additionally, the lamina helps to regulate the exchange of gases, such as carbon dioxide and oxygen, with the environment.
Function of pedicle and lamina in lumbar vertebrae?
The pedicle is a bony segment that connects the vertebral body to the lamina, forming the vertebral arch that protects the spinal cord. The lamina helps support the weight of the body and provides attachment points for muscles and ligaments. Together, the pedicle and lamina contribute to the stability and protection of the lumbar vertebrae.
Physical damage to the lamina propria of the nasal mucosa is likely to result in?
Physical damage to the lamina propria of the nasal mucosa can result in inflammation, bleeding, and impaired nasal function. The lamina propria plays a role in supporting the nasal epithelium and maintaining the nasal lining's barrier function. Damage to this layer can disrupt these functions and lead to symptoms such as nasal congestion, runny nose, and discomfort.
What is the structure and function of the lamina of a leaf?
The lamina of a leaf is the flat, expanded part of the leaf that is responsible for photosynthesis. It is made up of layers of cells that contain chloroplasts, which are the organelles that capture sunlight and convert it into energy for the plant. The lamina also helps to regulate the exchange of gases, such as carbon dioxide and oxygen, with the environment.
What is the nuclear wall?
The nuclear wall is not a scientifically recognized structure. It may refer to the nuclear envelope, a double membrane that surrounds the nucleus of eukaryotic cells, or it could be a misunderstanding of the nuclear membrane or nuclear lamina, which are components of the nuclear envelope.
The shape of the nucleus is maintained by?
The shape of the nucleus is maintained by the nuclear lamina, a mesh-like structure made of proteins called lamins that provide support and structure to the nucleus. This nuclear scaffold helps in organizing and maintaining the overall shape and function of the nucleus.
What maintains the shape o the nucleus?
The nuclear envelope, a double membrane structure, along with nuclear lamina and nuclear pore complexes help maintain the shape of the nucleus. The nuclear lamina provides structural support to the nucleus while the nuclear pore complexes regulate the entry and exit of molecules in and out of the nucleus.

What are the structure nucleus?
The nucleus is found in eukaryotic cells and its enclosed by a membrane. Its structures include a double membrane and the nuclear lamina.
What is the plural of lamina?
The plural form of lamina is laminae.
Physical damage to the lamina propria of the nasal mucosa is likely to result in?
Physical damage to the lamina propria of the nasal mucosa can result in inflammation, bleeding, and impaired nasal function. The lamina propria plays a role in supporting the nasal epithelium and maintaining the nasal lining's barrier function. Damage to this layer can disrupt these functions and lead to symptoms such as nasal congestion, runny nose, and discomfort.
What could happen if the nuclear lamina fall into disarray?
Disarray in the nuclear lamina, a network of proteins providing structural support to the nucleus, can lead to problems in maintaining the shape of the nucleus, disruption of nuclear envelope integrity, and altered chromatin organization. This can result in impaired nuclear functions such as gene expression, DNA replication, and cell division. Additionally, it may contribute to the development of certain diseases like progeria and muscular dystrophy.

What is the basal and reticular lamina?
The basal lamina is a thin extracellular layer that underlies epithelial and endothelial cells, providing structural support and aiding in cell adhesion. The reticular lamina, found beneath the basal lamina in some tissues, is primarily composed of collagen fibers and helps anchor the basal lamina to underlying connective tissue. Together, the basal and reticular laminae form the basement membrane, which plays a crucial role in tissue organization and function.
When was Elachista lamina created?
Elachista lamina was created in 1948.
When did Lamina Sankoh die?
Lamina Sankoh died in 1964.
