Thoracic limb

Last updated

A thoracic limb is a limb attached to the thorax. It may refer to one of these topics:

A limb, or extremity, is a jointed, or prehensile, appendage of the human or other animal body. In the human body, the upper and lower limbs are commonly called the arms and the legs, respectively. Arms and legs are connected to torso or trunk.

Thorax frontal part of an animals body, between its head and abdomen

The thorax or chest is a part of the anatomy of humans and various other animals located between the neck and the abdomen. The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain.

Upper limb arm (hand + forearm + upper arm + shoulder)

The upper limb or upper extremity is the region in a vertebrate animal extending from the deltoid region up to and including the hand, including the arm, axilla and shoulder.


A forelimb is an anterior limb on a terrestrial vertebrate's body. With reference to quadrupeds, the term foreleg is often used instead.

Anatomy The study of the structure of organisms and their parts

Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated over immediate (embryology) and long (evolution) timescales. Anatomy and physiology, which study (respectively) the structure and function of organisms and their parts, make a natural pair of related disciplines, and they are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine.

Fascia layer of fibrous connective tissue that surrounds muscles, blood vessels and nerves

A fascia is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs. Fascia is classified by layer, as superficial fascia, deep fascia, and visceral or parietal fascia, or by its function and anatomical location.

Gluteus minimus smallest of the three gluteal muscles

The gluteus minimus, the smallest of the three gluteal muscles, is situated immediately beneath the gluteus medius.

Subcallosal gyrus

The subcallosal gyrus is a narrow lamina on the medial surface of the hemisphere in front of the lamina terminalis, behind the parolfactory area, and below the rostrum of the corpus callosum. It is continuous around the genu of the corpus callosum with the indusium griseum. It's also considered a part of limbic system of brain.

Deltoid tuberosity

In human anatomy, the deltoid tuberosity is a rough, triangular area on the anterolateral (front-side) surface of the middle of the humerus to which the deltoid muscle attaches.

The lumbar enlargement is a widened area of the spinal cord that gives attachment to the nerves which supply the lower limbs.

The cervical enlargement corresponds with the attachments of the large nerves which supply the upper limbs.

Ventral ramus of spinal nerve

The ventral ramus is the anterior division of a spinal nerve. The ventral rami supply the antero-lateral parts of the trunk and the limbs. They are mainly larger than the dorsal rami.

Manus (anatomy)

The manus is the zoological term for the distal portion of the fore limb of an animal. In tetrapods, it is the part of the pentadactyl limb that includes the metacarpals and digits (phalanges). During evolution, it has taken many forms and served a variety of functions. It can be represented by the hand of primates, the lower front limb of hoofed animals or the fore paw and is represented in the wing of birds, bats and prehistoric flying reptiles (pterosaurs), the flipper of marine mammals and the 'paddle' of extinct marine reptiles, such as plesiosaurs and ichthyosaurs.

Descending limb of loop of Henle

Within the nephron of the kidney, the descending limb of loop of Henle is the portion of the renal tubule constituting the first part of the loop of Henle.

Ascending limb of loop of Henle

Within the nephron of the kidney, the ascending limb of the loop of Henle is a segment of the heterogenous loop of Henle downstream of the descending limb, after the sharp bend of the loop. This part of the renal tubule is divided into a thin and thick ascending limb; the thick portion is also known as the distal straight tubule, in contrast with the distal convoluted tubule downstream.

Fascial compartments of arm

The fascial compartments of arm refers to the specific anatomical term of the compartments within the upper segment of the upper limb(the arm) of the body. The upper limb is divided into two segments, the arm and the forearm. Each of these segments is further divided into two compartments which are formed by deep fascia – tough connective tissue septa (walls). Each compartment encloses specific muscles and nerves.

Anterior compartment of the forearm

The anterior compartment of the forearm contains the following muscles:

Triangular space Anatomic space of the upper body

The triangular space is one of the three spaces found at the axillary space. The other two spaces are the quadrangular space and the triangular interval.

Medial calcaneal branches of the tibial nerve

The medial calcaneal branches of the tibial nerve perforate the laciniate ligament, and supply the skin of the heel and medial side of the sole of the foot.

Medial intermuscular septum of thigh

The medial intermuscular septum of thigh is a fold of deep fascia in the thigh.

Lateral intermuscular septum of thigh

The lateral intermuscular septum of thigh is a fold of deep fascia in the thigh.

Leg weight bearing and locomotive anatomical structure, usually having a columnar shape, function as "extensible struts"

A leg is a weight-bearing and locomotive anatomical structure, usually having a columnar shape. During locomotion, legs function as "extensible struts". The combination of movements at all joints can be modeled as a single, linear element capable of changing length and rotating about an omnidirectional "hip" joint.
