Multifidus

What is multifidus?

The transversospinal group of deep back muscles includes the semispinalis, rotatores, multifidus, and other short, triangular muscles. They are shorter than semispinalis but longer than rotatores, and they are the thickest muscles in the transversospinal group. On either side of the vertebral column, from the cervical to the lumbar spine, there is a multifidus. Cervical multifidus, thoracic multifidus, and lumbar multifidus are the three regional subgroups of the group.

The spinal column is extended by the multifidus muscles. They contribute to the lateral flexion of the spine as well as some rotation of the vertebral bodies away from the side of contraction.

Multifidus: a muscle in the fifth and deepest layer of the back that helps to erect and rotate the spine by filling in the groove on either side of the spinous processes of the vertebrae from the sacrum to the skull.

Answer:

0.7

Explanation:

Using Hardy-Weinberg equation of genetic variation being constant when disturbing factors such has mutation and others are removed.

p² + pq + q² = 1 and p + q = 1

where p² is the frequency of the homozygous dominant genotype (RR) and q² is the frequency of the homozygous recessive genotype (rr) and 2pq is the frequency of heterozygous genotype (Rr). p represent the frequency of "R" and q represent "g". since the coefficient against the green/green homozygote is 0.30 then

the fitness of the green/green homozygote = 1 - 0.3 = 0.7

The epidermis is the most superficial layer of the skin. It is composed of stratified squamous epithelium. Within the epidermis,

son4ous [18]

Answer:

a. Stratum corneum 5. : Thick superficial layer of flat, keratinized, dead cells; responsible for dandruff.

b. Stratum granulosum 3.: Cells flatten and fill with keratin, resulting in a grainy appearance.

c. Stratum lucidum 4. : Clear layer found only in thick skin; cells full of keratin.

d. Stratum basale 1. : Deepest layer; site of rapid cell division and melanin production.

e. Stratum spinosum 2.: Live keratinocytes connected by desmosomes produce pre-keratin

Explanation:

The epidermis has five layers, starting from the deepest one they are:

The stratum basale: is the layer that has the germinative cells, called keratinocytes.

The stratum spinosum: the keratinocytes are connected, and they produce the precursor of keratin and lipids.

The stratum granulosum: the name of this stratum is due to the appearance of the cells. They produce keratohyalin, and the lipids produced in the previous layer are released, creating the layer that protects the skin against dehydration.

The stratum lucidum: They are only in thick skin, like the one that is in the sole of our feet. The cells do not have a nucleus. They are filled with keratin, which is the component of thick skin.

The stratum corneum: the more superficial layer, it is made of dead cells filled with keratine. When new cells ascend to this stratum, the old ones have to be removed by exfoliation or natural peeling.

makkiz [27]

The initiating event in the development of nephrotic syndrome is a derangement in the glomerular membrane that causes increased permeability to plasma proteins.

Nephrotic syndrome can be understood as a kidney disorder in which the glomeruli filter of the kidney gets damaged due to which it is unable to filter the proteins and passes an excess amount of protein in the urine.

Glomeruli filter consists of clusters of small blood vessels in the kidneys that function in filtering the waste and excess water from the blood. It also sweeps the blood protein which is necessary to maintain the correct amount of fluid in the body, from seeping into the urine. But when it gets damaged glomeruli stop sweeping the protein from the urine as a result too much blood protein leaves your body, leading to nephrotic syndrome.
