The ischium bone forms the superior part of the pelvic girdle.
<h3>What is the structure of the pelvic girdle?</h3>
In the bottom region of the trunk, there is a bony structure known as the pelvic girdle that resembles a ring. It joins the lower limbs to the axial skeleton. There are two types of pelvises: the bigger pelvic and the lesser pelvis.
The pelvis is made up of two paired hipbones that are joined at the pubic symphysis in front and by the sacrum in back. Each hipbone is composed of three bones: the blade-shaped ilium above and to either side, which determines the hips' width; the ischium below, on which the weight is placed when sitting; and the pubis in front. Early in maturity, all three come together at a triangle suture in the acetabulum, the cup-shaped socket that connects to the head of the femur to create the hip joint.

Answer:
Muscle contraction function.
Explanation:
The nerve endings possess synaptic acetylcholine vesicles ready to be released. The action potential depolarizes the presynaptic terminal and increases the concentration of axoplasmic calcium; Acetylcholine molecules are thus released, so that the concentration of the neurotransmitter at postsynaptic (nicotinic) receptors is temporarily increased. This is followed by post-synaptic membrane depolarization, muscle membrane action potential with increased rnioplasmic calcium concentration, and finally muscle contraction. Acetylcholine is hydrolyzed by acetylcholinesterase and resynaptic at the presynaptic level by cholinecetyltransferase. The etiopathogenesis of myasthenia gravis is autoimmune and there are antibodies against acetylcholine receptors that circulate in the blood, as well as a decrease in the number of receptors on the motor plates, that is, it is produced by the postsynaptic blockage of the myoneural plaque, that generates fatigue and localized or generalized muscle weakness that is characterized by the worsening of the contractile force of the muscle.
Both are made up of cells, charisma has a goldfish she keeps in a tank. she planted several underwater plants in the bottom of the tank.
<h3>How long do goldfish live for?</h3>
Goldfish have a lifespan Of about 10-15 years, with some sorts living up to 30 years when occupied with proper maintenance.
Thus, Both are made up of cells.

Ribosomes are attached to<span> the </span>membrane<span> of the </span>ER, making it “rough<span>.” The RER is also </span>attached to<span> the nuclear envelope that surrounds the nucleus.</span>
Phospholipids have a hydrophilic(water-liking) ‘head’ and a hydrophobic ‘tail’ so they are amphipathic. They form a lipid bilayer because of their amphipathic properties. The tails get sandwiches between the hydrophilic heads that are able to interact with water.
Hope this helps:)
