(FAS). Mothers who consume alcohol anytime during pregnancy‚ puts their children at risk for multiple constellations of abnormalities when they are born. A common condition observed in children affected is optic nerve hypoplasia‚ which basically is the underdevelopment of the optic nerve during pregnancy. The affected child has abnormal shaped eyes that appear closer together‚ which can contribute to the poor visual acuity and their dysmorphic facial features shown up to ninety percent of the births

Question: Identify the muscles in the anterior compartment of the leg The leg is divided into three compartments by tough fasciae to hold the muscles and proper functioning of these muscles during their contraction. These compartments also contain nerves and vessels. The three main compartments are anterior (extensor)‚ lateral (fibular) and posterior (flexor). The anterior compartment (Extensor compartment) contains muscles which are used for extension (dorsiflexion) of the foot as these muscles have

is an area of skin that is mainly supplied by a single spinal nerve. There are eight cervical nerves (C1 being an exception with no dermatome)‚ twelve thoracic nerves‚ five lumbar nerves and five sacral nerves. Each of these nerves relays sensation (including pain) from a particular region of skin to the brain. Along the thorax and abdomen the dermatomes are like a stack of discs forming a human‚ each supplied by a different spinal nerve. Along the arms and the legs‚ the pattern is different: the

when the roots of the sciatic nerve are cut * As we cut the root of the right sciatic nerve of the frog in the experiment‚ the right lower leg of the frog becomes limp. The right gastrocnemius muscle lost its firmness and becomes flabby while I have observed as we compared the tonicity of the muscles with the left gastrocnemius muscle (with the root of left sciatic nerve is still intact) it is different. The left gastrocnemius muscle remains firm with the sciatic nerve connected. This observation
