Name the 6 sets of extraocular muscles and the cranial nerve that innervates each one.
6 sets of extraocular muscles and cranial nerves that innervate each one is:
Cranial nerve three; superior oblique, superior rectus, inferior oblique, inferior rectus,
Cranial nerves four; medial rectus,
Cranial nerve six; lateral rectus.
The seven extrinsic muscles of the human eye are known as the extraocular muscles (extrinsic ocular muscles). Six of the extraocular muscles, the four recti muscles, the superior and inferior oblique muscles, and the levator palpebrae superioris, govern eye movement and eyelid raising, respectively. The six eye muscles' actions are influenced by the position of the eye at the moment of muscle contraction.
The four recti muscles are the four extraocular muscles that originate in the common tendinous ring, a fibrous ring in the back of the orbit. Because both muscles also pull slightly medially, the superior and inferior recti do not draw on the eye directly. The superior oblique muscle begins near the back of the orbit (a little closer to the medial rectus, though medial to it), becoming more rounded as it moves forward to a hard, cartilaginous pulley on the top, nasal bone called the trochlea.

How many degrees celsius does a 1.5 gram block of ice increase when 30.0 J of heat energy is added?
(Cp = 2.11 J/g°C)
Degrees celsius does a 1.5-gram block of ice increase when 30.0 J of heat energy is added is 9.48 °C.
Heat may be described as strength in transit from a high-temperature object to a decreased-temperature object. An item no longer possesses warmness, the perfect term for the microscopic electricity in an object is internal energy.
Heat is the shape of energy. It comes from the movement of atoms and molecules, which can be the smallest particles that make up all matter. The quicker those debris circulate, the hotter they are. The temperature of an object tells us how speedy its atoms or molecules are transferring. Warm is a form of electricity that is transferred from a substance having a better temperature to a substance having a decreased temperature. The addition of warmth to a substance increases its internal temperature. warmness is described because of the net amount of thermal energy of a gadget.
The heat energy required = msΔt

Progesterone. It is a steroid hormone in charge of sustaining and decidualizing the endometrium.
What is a corpus luteum?
An ovary's corpus luteum is a collection of cells. During the first trimester of pregnancy, it is in charge of producing the hormone progesterone. In females, the corpus luteum is essential for establishing and maintaining pregnancy.
It is a yellow, hormone-secreting body that develops in the ovary at the site of the sac that has discharged after the egg has reached maturity during the process of ovulation. It is located in the female reproductive system. The granulosa cells that border the follicle begin to accumulate lipids and yellow pigments right after ovulation, which causes the development of lutein cells, which make up the corpus luteum.
Progesterone and estrogen are secreted by the corpus luteum. In the event of fertilization, they are crucial in creating changes in the uterus that make it more favorable for embryo-implantation; otherwise, it becomes dormant after about 14 days, resulting in menstruation.
