In contrast to mosses (Phylum Bryophyta)‚ the vascular plant sporophyte is dominant over AND is functionally independent of the gametophyte. • Conductive (vascular) tissues are universal AND are present in the sporophyte (not the gametophyte). • Although mosses live in moist environments (at least some of the time)‚ some vascular plants have acquired relative independence of free water. • Some vascular plants survive in harsh conditions (including hot and cool deserts). Ferns belong to the Phylum

The endothelial barrier strictly maintains vascular and tissue homeostasis‚ and therefore modulates many physiological processes such as angiogenesis‚ immune responses‚ and dynamic exchanges throughout organs. Consequently‚ alteration of this finely tuned function may have devastating consequences for the organism. This is particularly obvious in cancers‚ where a disorganized and leaky blood vessel network irrigates solid tumors. In this context‚ vascular permeability drives tumor-induced angiogenesis

Cerebral palsy remains one of the most common debilitating diseases in the world. Factors such as neuromuscular incoordination‚ use of soft diet and delayed oral clearance of food make maintenance of optimum oral hygiene a challenging task in these children. The compromised oral hygiene in turn make these children highly vulnerable to dental disease. Maintaining optimal oral/dental health in CP children is of utmost importance as these children usually suffer from several associated general health

Cerebral Palsy (CP) is a condition that affects thousands of people each year. An estimated 764‚000 children and adults are afflicted with one or more symptoms of CP. Around 8‚000 infants and babies are diagnosed each year and 1‚200-1‚500 preschool age children are recognized with symptoms of CP (www.ucp.org). This condition is caused by “abnormal development of areas of the brain that control movement and posture” (www.ucp.org). It can also be caused by damage to the brain (usually because

Cerebral Palsy Causes Cerebral palsy results from damage to certain parts of the developing brain. •This damage can occur early in pregnancy when the brain is just starting to form‚ during the birth process as the child passes through the birth canal‚ or after birth in the first few years of life. •In many cases‚ the exact cause of the brain damage is never known. At one time‚ problems during birth‚ usually inadequate oxygen‚ were blamed for cerebral palsy. •We now know that fewer than

Cerebral Palsy Cerebral Palsy (CP) is a term used to describe disorders of movement that result from injury to the brain. It is a problem of muscle coordination. Cerebral Palsy can be caused by numerous problems occurring in the prenatal period‚ prematurity‚ labor and delivery complication in the newborn period. Due to genetic or chromosomal abnormality to the brain may not develop in the typical way. Some environmental factors such as drugs metabolic problems and placental dysfunction may also

Cerebral Palsy Cerebral Palsy is a disorder of movement‚ muscle tone or posture. It affects the ability to move in a coordinated and purposeful way. The exact cause is unknown‚ but many cases are the result of problems during pregnancy in which the brain is damaged or it does not develop normally. It can be caused from anything that interferes with normal brain development such as infections and maternal health problems. It usually occurs before or during birth‚ or during the first 3 to 5

Cerebral palsy CP is a disorder of aberrant control of movement and posture‚ appearing early in life secondary to a CNS lesion or dysfunction that is NOT a result of a progressive or degenerative brain disease. In other words‚ CP is caused by a static brain dysfunction (also called static encephalopathy). It is believed that CP is due to a defect in a developing brain‚ a lesion that may have had its onset in prenatal‚ perinatal‚ or postnatal period. Thus‚ causes of CP may be manifold.

Cerebral palsy encompasses a group of conditions that are caused by problems in brain development. Disturbances in the brain usually occur during fetal or infant brain development and effects movement and motor control in children (Lisovska‚ 2016). The cerebral cortex‚ which is the part of the brain responsible for directing muscle movement‚ is damaged and cerebral palsy thus develops. Cerebral palsy can be classified into four types which are made distinct because of its location and abnormality
