Thorax (insect anatomy) The thorax is the midsection of the insect body. It holds the head, legs, wings and abdomen. It is also called mesosoma in other arthropods. It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that separates the head from the thorax; and the pleuron, a lateral sclerite of the thorax.

Thorax (insect anatomy) Members of sub order Apocrita (wasps, ants and bees) in the order Hymenoptera have the first segment of the abdomen fused with the thorax, which is called the propodeum. In most flying insects, the thorax allows for the use of asynchronous muscles.

Jean-Baptiste Lamarck's Theory of Evolution: Overview Video: Jean-Baptiste Lamarck's Theory of Evolution: Overview. You might know about Charles Darwin and his theory of evolution. However, it was the lesser known, yet influential, Jean-Baptiste Lamarck who put forth a theory that laid the early foundations for the study of evolution.

Body cavities and membranes Membranes in the Ventral body cavity. The walls of the ventral body cavity and outer covering of its organs contain a thin covering called the serosa (also called serous membrane). It is a double-layered membrane made up of two parts called the “parietal serosa” (lines the cavity walls) and “visceral serosa” (covers organs in the cavity). The serous membranes are separated by a thin layer of fluid called “serous fluid“.

The male will have a rounded segment that is not pointy and long at the end of his body.

Cervix Structure[edit] Diagram of the uterus and part of the vagina. The cervix is the lower part of the uterus situated between the external os (external orifice) and internal os (internal orifice). The cervical canal connects the interior of the vagina and the cavity of the body of uterus.

Do wasps shed their shell like cicadas? There is a worm or grub-like larva, then a pupa, then the adult. Wasp larvae look like maggots, and they shed their skins too. The final larval instar will shed its skin and become a pupa, and they sometimes do this inside a silken cocoon (the cocoon is not part of the insect: the pupa is inside it). Other wasps just form a pupa inside the cell in their hive, like bees, or inside or on their parasitized prey.

Rat Anatomy - The Thoracic Organs 1. Locate the diaphragm, which is a thin layer of muscle that separates the thoracic cavity from the abdominal cavity. 2. The heart is centrally located in the thoracic cavity. The two dark colored chambers at the top are the atria (single: atrium), and the bottom chambers are the ventricles.

- The cephalothorax is the first of 2 body parts on a spider. It is a combination of the head and thorax, and on it are found the legs, eyes, pedipalps, chelicerae, and other mouthparts. Among arachnids that live in Kentucky (including scorpions, daddy-long-legs, and mites) only spiders have this thin stalk between the abdomen and cephalothorax.

Picture of the Cervix The cervix is a cylinder-shaped neck of tissue that connects the vagina and uterus. Located at the lowermost portion of the uterus, the cervix is composed primarily of fibromuscular tissue. The part of the cervix that can be seen from inside the vagina during a gynecologic examination is known as the ectocervix. An opening in the center of the ectocervix, known as the external os, opens to allow passage between the uterus and vagina.

What is the pleural membrane? exists and is an alternate of . The pleural membrane is a double-layered serous membrane found in the thoracic cavity. The outer layer is called the parietal pleura and lines the thoracic wall, and the inner layer is called the visceral pleura and covers the lungs. The membranes produce lubricating serous fluid that causes them to adhere closely to one another.

Picture of the Cervix The endocervix, or endocervical canal, is a tunnel through the cervix, from the external os into the uterus. The overlapping border between the endocervix and ectocervix is called the transformation zone. The cervix produces cervical mucus that changes in consistency during the menstrual cycle to prevent or promote pregnancy.

Guinean forest-savanna mosaic  [show article only] hover over links in text for more info Tortoises are shielded from predators by a shell. The top part of the shell is the carapace, the underside is the plastron, and the two are connected by the bridge. The carapace is fused to both the vertebrae and ribcage, and tortoises are unique among vertebrates in that the pectoral and pelvic girdles are inside the ribcage rather than outside.

What's the difference between bees and wasps? While bees have robust, hairy bodies with flat rear legs, wasps' bodies are slender with a narrow waist connecting the thorax and abdomen. (The thorax and abdomen are the names given to an insect's mid and rear segments.) In addition, wasps appear smooth and shiny and have slender legs shaped like cylinders.

Rat Anatomy - The Thoracic Organs Once you have opened the body cavity, you will need to rinse it in the sink. 1. Locate the diaphragm, which is a layer of muscle that separates the thoracic from the abdominal cavity. 2. The heart is centrally located in the thoracic cavity.The two dark colored chambers at the top are the atria (single: atrium), and the bottom chambers are the ventricles.. The coelom is the body cavity within which the viscera (internal organs) are located. The cavity is covered by a membrane called the peritoneum, which is very thin and web-like, you may need to use forceps to remove some of this membrane to see the organs clearly.

Arthropoda - Crustaceans, Insects Most arthropod's bodies have three sections-the head, the thorax, and the abdomen. The thorax is the part of the body between the head and the abdomen. In some species of arthropods, the head and the thorax are one section called the cephalothorax. Arthropods have an open circulatory system.

Pleural cavity The outer pleura (parietal pleura) is attached to the chest wall, but is separated from it by the endothoracic fascia. The inner pleura (visceral pleura) covers the lungs and adjoining structures, including blood vessels, bronchi and nerves.

- As the acrosome reaction progresses and the sperm passes through the zona pellucida, more and more of the plasma membrane and acrosomal contents are lost. By the time the sperm traverses the zona pellucida, the entire anterior surface of its head, down to the inner acrosomal membrane, is denuded.

Pleural Cavity and Membranes - Anatomy & Physiology The visceral pleura which coats the outer surface of the lung is derived from the splanchnic mesoderm. The parietal pleura lining the thoracic cavity is derived from somatic mesoderm. The pleural cavity is a potential space between the two areas of pleural membrane, which normally are adhesed to each other.ach lung is placed within a separate layer of membrane, thus there are two pleural sacs. The space between the two sacs is known as the mediastinum, and is almost in the midline of the thorax. The pleura covering the surface of the lung is known as pulmonary pleura or visceral pleura.

Body cavities and membranes The abdominopelvic cavity is also separated into two subdivisions, the “ abdominal cavity ” and “ pelvic cavity “. The abdominal cavity contains the stomach, spleen, liver, intestines, and a few other organs.he walls of the ventral body cavity and outer covering of its organs contain a thin covering called the serosa (also called serous membrane). It is a double-layered membrane made up of two parts called the “ parietal serosa ” (lines the cavity walls) and “ visceral serosa ” (covers organs in the cavity).

Regions of the Thorax Therefore, the thorax can be defined as consisting of the thoracic cavity, its contents including the primary organs of the respiratory and cardiovascular systems, and the wall that surrounds it. It is the part of the trunk between the neck and abdomen. The thorax is composed of a ventral and a dorsal surface.
