How does spinal fusion work?
Spinal fusion involves techniques designed to mimic the normal healing process of broken bones. During spinal fusion, your surgeon places bone or a bonelike material within the space between two spinal vertebrae. Metal plates, screws and rods may be used to hold the vertebrae together, so they can heal into one solid unit.
What is a two-level fusion of the spinal cord?
A two-level fusion may be considered for patients with severe, disabling pain that occurs at two levels of the spine (e.g. L4-L5 and L5-S1) after extensive non-surgical and pain management approaches have been tried.
What is the difference between single level and multilevel fusion?
Fusion Overview. Fusion of only one motion segment of the spine (e.g. L5-S1) is referred to as a single level fusion. Multilevel spinal fusion refers to fusion of more than one spinal disc level (e.g. L3-L4 and L4-L5 fusions). When a multilevel spinal fusion is performed, it is almost always on contiguous spinal levels.
What is double and triple fusion?
One male gamete fuses with the female gamete and the other fuses with the secondary nucleus. As two male gametes take part and fertilization and fertilization takes place twice, this process is called double fertilization. Since three gametes are involved it is called triple fusion.
What is triple fusion?
Definition of triple fusion : the fusion involving two polar nuclei and a sperm nucleus that occurs in double fertilization in a seed plant and results in the formation of the endosperm.
What is double fertilization 10th?
What is Double Fertilization? Double fertilization is a chief trait of flowering plants. In the phenomena, one female gamete unites with two male gametes. One of the male gametes fertilizes the egg resulting in the formation of a zygote and the other unites with 2 polar nuclei for the formation of an endosperm.
Why is it called double fertilization?
This process is called syngamy. The other sperm nucleus fuses with polar nuclei to form endosperm. This process is called triple fusion. Since two kinds of fusion, syngamy and triple fusion take place, the process is known as double fertilisation.
What is called syngamy?
Definition of syngamy : sexual reproduction by union of gametes : fertilization.
What is syngamy and triple fusion?
Syngamy is fusion of one of two male gametes with egg to produce diploid zygote. It is also known as generative fertilisation or true fusion. Triple fusion is the fusion of second male gamete with two haploid polar nuclei to form triploid primary endosperm nucleus. It is also known as vegetative fertilisation.
What is triple fusion class 10th?
Triple fusion is a fusion that involves a sperm nucleus and two polar nuclei which occurs in the double fertilization in a seed-bearing plant that results in the endosperm formation.
Why is Apple called a false fruit?
False fruits develop from any other part of the plant except ovary. Parts of fruit include exocarp, mesocarp, and endocarp. As Apple does not grow from the ovary, it is a false fruit.
What is triple fertilization Class 12?
Triple fusion is the fusion of the male gamete with two polar nuclei inside the embryo sac of the angiosperm. This process involves the fusion of three haploid nuclei, hence it is known as triple fusion. It results in the formation of the endosperm.
What is double fertilization example?
Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm).
How zygote is formed?
A zygote is a fertilized egg. It's created when sperm meets an egg in one of the fallopian tubes. When the sperm enters the egg, you conceive and the result is the zygote. It contains all the genetic information (DNA) that's required to create a little human being.
Who discovered double fertilization?
NawaschinSummary. The fusion of one sperm with the egg cell to form the embryo and of the other sperm with the polar fusion nucleus to give rise to the endosperm ('double fertilization') was discovered by Nawaschin in 1898 in the liliaceous plants, Lilium martagon and Fritillaria tenella.
Why is it called triple fusion?
It is called triple fusion due to the presence of 3 nuclei one from the sperm nuclei and two nuclei of polar nuclei. The fusion involves the two polar nuclei and a sperm nucleus that occurs in double fertilization leads to formation of endosperm.
What is the importance of triple fusion?
The result of the triple fusion is the formation of a triploid nucleus called a primary endosperm nucleus. This nucleus by repeated mitotic divisions gives rise to the formation of the endosperm This endosperm provides nourishment to the developing embryo.
What is the product of Triple Fusion?
the endospermThe product of the triple fusion process is the formation of the endosperm. Endosperm tissue is present inside the seeds of the flowering plants which is then used in the fertilization. It provides essential nutrients to the in form of starch.
Who discovered triple fusion?
Nawaschin and Guignard- Now, the double fertilization and the triple fusion is first discovered by Nawaschin and Guignard.

Why do you need spinal fusion?
Why it's done. Spinal fusion permanently connects two or more vertebrae in your spine to improve stability, correct a deformity or reduce pain. Your doctor may recommend spinal fusion to treat: Deformities of the spine. Spinal fusion can help correct spinal deformities, such as a sideways curvature of the spine (scoliosis).
Where is spinal fusion performed?
During spinal fusion. When spinal fusion is performed from the back of the neck (posterior cervical fusion), rods and screws are used to hold the vertebrae together. In some cases, surgery on your neck (cervical) vertebrae occurs from the front (anterior) side of your neck.
How to fuse vertebrae?
Fusion. To fuse the vertebrae together permanently, the surgeon places the bone graft material between the vertebrae. Metal plates, screws or rods may be used to help hold the vertebrae together while the bone graft heals. In selected cases, some surgeons use a synthetic substance instead of bone grafts.
Is spinal fusion effective?
Spinal fusion is typically an effective treatment for fractures, deformities or instability in the spine. But study results are more mixed when the cause of the back or neck pain is unclear. In many cases, spinal fusion is no more effective than nonsurgical treatments for nonspecific back pain.
Is spinal fusion surgery safe?
Risks. Spinal fusion is generally a safe procedure. But as with any surgery, spinal fusion carries the potential risk of complications. Potential complications include: Infection. Poor wound healing. Bleeding. Blood clots. Injury to blood vessels or nerves in and around the spine.
Can you be unconscious during spinal fusion?
Surgeons perform spinal fusion while you're under general anesthesia so you're unconscious during the procedure. Surgeons have developed a variety of techniques for performing spinal fusion surgery. The technique your surgeon uses depends on the location of the vertebrae to be fused, the reason for the spinal fusion, and in some instances, your general health and body shape.
Does spinal fusion help with back pain?
Even when spinal fusion provides symptom relief, it does not prevent you from developing more back pain in the future. Most of the degenerative conditions in the spine are caused by arthritis, and surgery will not cure your body of that disease.

Why do surgeons do multilevel spinal fusions?
In addition to treatment for severe low back pain, there are many different reasons that surgeons perform multilevel spinal fusions. One common indication is for the treatment of spinal deformity, including scoliosis (side curvature of the spine), kyphosis (forward bending of the spine), and spondylolisthesis (forward slippage of one vertebra on another). In addition, multilevel spinal fusions are often performed in the treatment of the less commonly seen fractures, tumors, and infections of the spine.
Why does a 3 level fusion cause pain?
Too much rigidity. Three level fusions limit movement and flexibility in the patient’s back so much that this in and of itself is likely to cause pain.
What are the most common levels of spinal fusion?
The most common levels included in a multilevel spinal fusion are L4-5 and L5-S1. advertisement.
Is a multilevel spinal fusion necessary?
While multilevel spinal fusions are a common and necessary procedure to treat many types of spinal pathology, such as scoliosis or other types of deformity, for treatment of low back pain from lumbar degenerative disc pathology this type of procedure remains controversial.
Is fusion surgery for lumbar degeneration surgery an option?
For example, a fusion from L3 through S1 would put the L2-L3 level of the spine at risk for degeneration and causing future pain. Because of the above, some physicians believe that lumbar degenerative disc disease at three or more levels of the spine means that fusion surgery is not an option. Instead, patients with severe pain ...
