The muscular systems consist of a deltoid, latissimus dorsi, and a trapezius muscle. The wolf’s trunk muscles are used for them to run and leap. 1. Neck muscles hold the head. 2. The jaw muscles are used when they bite their prey when they attack. The three types of muscles are the smooth, cardiac, and the skeletal. 1. The smooth muscle lines the internal organs. Such as the intestine, bladder, uterus and large blood vessels. 2. Cardiac muscles It keeps the wolf’s heart beating. 3. Skeletal muscle is under voluntary control.

The male wolf has a penis. There is a special bone is the penis called the baculum. The penis has the testes hang between the back legs in a scrotal sack. This sack is lightly furred. 3. Both the male and female wolves have eight nipples on their chest and belly. The difference is females can only produce milk. 4. The female wolf has two egg-producing ovaries. The fallopian tube leads to the uterus. When a female wolf is pregnant, her uterus can expand to fit up to eleven cubs. The mating process of the reproductive system starts as follows: 1. The male wolf’s penis swells inside the female. The wolves are then locked together for about half an hour. 2. The male wolf produces sperm which passes from the testes, through what is called the vasa deferentia, and then to the penis. 3. The sperm cell contains three different organelles, these include the nucleus, the mitochondria, and the acrosome. Then the penis then ejaculates the sperm into the female. 4. When the female wolf eggs are released from two ovaries. They pass along the ovarian ducts to the uterus. 5. The female wolf egg cells contain mitochondria, ribosomes, and a nucleus. Fertilization takes place at any time after the eggs are
The Neovison vison dissection lab was intended so students could study the external and internal anatomy and physiology of the Neovison vison. Once the Neovison vison was dissected, students could see the similar and different characteristics of the Neovison vison that are present within the human body. Students were able to identify muscles, bones, organs, tissues, insertion points, and origin points within the body of the animal. Reflection on skeletal and muscular structure was also studied throughout the dissection lab. Although the muscles within the Neovison vison and the skeletal structure of the Neovison vison are highly similar to those in a human body, this dissection lab made it known that there truly are anatomical differences within
P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue.
The integumentary system- This system is overlaying the outer body. • Anatomical location- The integumentary system is superior or external to the body. The organs that make up this system are the skin, glands, nails, hair, and sense receptors.
Mexican gray wolves usually stay in habitats like mountain forests. They once ranged from central Mexico throughout the southwestern U.S before its extinction. Wolves are very social animals. They live in packs like any other wolves would most likely live like. When they reproduce pups are born blind and defenseless.
Because red wolves can live in many different habitats, there main limiting factors are the amount of prey and human interactions within those
They have a very diverse habitat. They are also able to live with very large animals including elk, moose, and bears. That is a wolves habitat and niche. The food web is an important part of an ecosystem.
The article “Only 3 Wolves Left on Michigan’s Isle Royale” written by Keith Matheny quotes John Vucetich saying, “The three remaining wolves on the island are likely a mated pair and their offspring.” The article also implies that this family is in the same pack. This single pack could easily turn into multiple packs if we place more wolves on Isle Royale. The new wolves would increase the population, and if the population increases, more packs would need to form in order to divide the population into manageable
The gray wolf 's expressive behavior is more complex than that of the coyote and golden jackal, as necessitated by its group living and hunting habits. While less gregarious canids generally possess simple repertoires of visual signals, wolves have more varied signals which subtly inter grade in intensity.[12][13] When neutral, the legs are not stiffened, the tail hangs down loosely, the face is smooth, the lips untensed, and the ears point in no particular direction.[135] Postural communication in wolves consists of a variety of facial expressions, tail positions and piloerection.[120] Aggressive, or self-assertive wolves are characterized by their slow and deliberate movements, high body posture and raised hackles, while submissive ones carry their bodies low, sleeken their fur and lower their ears and tail.[136] When a breeding male encounters a subordinate family member, it may stare at it, standing erect and still with the tails horizontal to its spine.[137] Two forms of submissive behavior are recognized: passive and active. Passive submission usually occurs as a reaction to the approach of a dominant animal, and consists of the submissive wolf lying partly on its back and allowing the dominant wolf to sniff its anogenital area.
A wolves muzzle is large and squared, and a coyotes is smaller and pointed. As far as their ears, a gray wolves is rounded and relatively short, while a coyotes is pointed and relatively long. A gray wolves coat usually ranges between

The Howler Monkeys use their tail to help them grip onto branches as one tries to eat and move around the same in treetops. The tail of a howler monkey acts as a fifth limb for them, which is very ideal for their movement through the
There are four steps in the muscle contraction cycle. At the beginning of contraction, the sarcoplasmic reticulum releases ca2+ into the sarcoplasm where they will bind to troponin. Troponin then moves tropomyosin away from the myosin binding sites on actin. Once binding sites are free the contraction cycle will begin. Step one of the contraction cycle is ATP Hydrolysis.
There are millions of these cells inside the human body, and each has a different type of responsibility, or function. There are an infinite amount of cell types, and a few examples of these types are: 1) muscle cells, 2) nerve
Sexual reproduction is most common type of reproduction among the plants and animals. They are of following types; 1) Syngamy: The fusion of gametes takes place completely, if male and female gametes are produced by same cell or organism and both gametes fuse together to form a zygote, this is called as Autogamy, paramecium is its example. Another is Anisogamy in which some organisms produce two types of gametes. Both types of gametes differ from each other in their shape and size and are known as an isogametes or heterogametes. Male gametes are motile and small in size and are known as micro gametes.
