What is the function of an earthworms testes?
to release eggsfemale gonad in which eggs are produced
What are the reproductive parts of an earthworm?
All worms have both male reproductive organs and female reproductive organs. This means that they are hermaphrodites. The female organs of a worm include the egg sacs and ovaries. The male organs are two pairs of testes, three pairs of seminal vesicles and sperm funnels. Despite the fact that worms have both male and female organs; it must mate with another worm in order to reproduce its own kind.
Where is the nervous tissue located in the heart?
Sympathetic innervation of the heart is from cardiac accelerator nerves descending from the uppermost thoracic sympathetic ganglia and the cervical sympathetic ganglia. Parasympathetic innervation comes from the vagus nerve (Cranial Nerve X). These nerves continue into the walls of the heart and provide autonomic innervation, which can only modify the rate and contractility of the heart. Inside the heart, intrinsic pacemaking comes from the sinoatrial node, which automatically paces the heart due to the existence of "funny currents" (seriously, that's what they're called) that depolarize the node. The SA node is located in the right atrium and the depolarization follows tracks to the left atrium and the atrioventricular node. The AV node can automatically depolarize, but it does so at a lower rate than the SA node, so the SA node overrides the AV nodal rhythm. From the AV node, the electrical signal goes through Bundles of His and Purkinje Fibers to deliver a wave of depolarization to the cardiac muscle. These cells are modified cardiac myocytes between the endocardium and the myocardium specialized for the transmission of electrical impulse. Technically, these are not nerves, though they function similar to nerves. Beyond that, there are gap junctions between cardiac myocytes in the intercalated disks that allow for the coordinated contraction of cardiac muscle. In other words, the cells are arranged like a net and the depolarization and contraction of one cell leads to the depolarization and contraction of the cells next to it that have not yet been depolarized.

It is advantageous to have human testes in the scrotum rather than in the abdomen due to?
It's due to the cooling effect of having the testes outside the main portion of the body. Testes need a slightly lower temperature than the rest of the body, for ideal functioning. Overheating will reduce fertility.
Why are the testes contained in a sac?
Most male mammals have testes in an external sac in order to protect their sperm from overheating. Excessive heat can impair sperm, negatively affecting fertility.
What is Pertaining to the testes?
Testes
Male sheep castration what are its affect while band is placed?
The band that is placed on the neck of the scrotum (NOT right on the testes, as this will be VERY painful for the ram), and this cuts off the nerves and blood supply to the testes. After a few weeks, gangrene occurs (but no infection occurs in the ram because the tight rubber rings prevents this), and the testes fall off. The pain is short-term right after the band is placed, but soon this goes away.
What is the synonym of testes?
Testicles is the synonym for testes.
Why does a bull's testicles hang lower from the body than a horse's?
There are two reasons why. First of all, horses are animals that love to run. In order to prevent the testes from getting damaged and bruised from running, they are tucked up closer to the body. Cattle are typically too bulky and heavy to run (though there is no doubt that they are capable of running quite fast), so the testes are allowed to hang down a bit more. The second reason is that the longitudinal length of the testes of a stallion are positioned parallel to the line of the underside of the belly or the ground. This prevents the scrotum from allowing the testes to hang down so much and, anatomically speaking, makes the testes have to be held closer to the body. With a bull, on the other hand, the testes are perpendicular to the ground.
What is the function of female testes?
Females do not have testes. Testes are male reproductive organs. The female equivalent of testes is ovaries, which produce eggs and female sex hormones.
Why must the testes be outside of the abdominal cavity?
The temperature needed for the sperms to survive and thrive is lower than the optimum body temperature , hence it is not possible to maintain a lower temperature inside the body hence the testes are located outside the body.
What is made in the testes?
The testes produce spermatozoa (sperm).
What does the testes produce?
The testes produce the hormone testosterone.Testosterone
Where are the sperm produced in a male frog?
That is not the answer. The answer is Testes.
What hormone secretes the testosterone?
Testosterone IS a hormone. It is secreted by the testes.
