The Appendicular Skeleton Flashcards
What is a clavicle?
In human anatomy, the clavicle or collarbone is a long bone of short length that serves as a strut between the scapula and the sternum. It is the only long bone in the body that lies horizontally.
What is the appendicular skeleton?
The appendicular skeleton is composed of 126 bones in the human body. The word appendicular is the adjective of the noun appendage, which itself means a part that is joined to something larger. Functionally it is involved in locomotion (lower limbs) of the axial skeleton and manipulation of objects in the environment (upper limbs).
What is a scapula?
In anatomy, the scapula, or shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone).
What is the humerus?
The humerus is a long bone in the arm or forelimb that runs from the shoulder to the elbow. Anatomically, in modern humans, it connects the scapula and the lower arm (consisting of the radius and ulna).
What is the ulna?
The ulna or elbow bone is one of the two long bones in the forearm, the other being the radius. It is prismatic in form and runs parallel to the radius, which is shorter and smaller.
What is the radius?
The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna, which exceeds it in length and size.
What is a carpus?
Carpus is anatomical assembly connecting the hand to forearm. In human anatomy, the main role of the carpus is to facilitate effective positioning of the hand and powerful use of the extensors and flexors of the forearm, but the mobility of individual carpal bones increase the freedom of movements at the wrist.
What are the metacarpus?
In human anatomy, the metacarpus is the intermediate part of the hand skeleton that is located between the phalanges (bones of the fingers) and the carpus which forms the connection to the forearm. The metacarpus consists of metacarpal bones. Its equivalent in the foot is the metatarsus.
What are the proximal phalanges?
Proximal phalanges or singular, “proximal phalanx”, are bones found in the limbs of most vertebrates. In humans, they are the bones proximal to the base of a toe or finger, the prominent, knobby ends of which, on the hands, are often called the knuckles.
What are the intermediate phalanges?
Intermediate phalanges are bones found in the limbs of most vertebrates. In humans, they are the bones of the finger and toe which lie in the middle, between the two wrinkly joints. The thumb and big toe do not have intermediate phalanges.
What are the distal phalanges?
The distal or terminal phalanges are the terminal limb bones located at the tip of the digits (i.e. fingers and toes). In human anatomy, the distal phalanges of the four fingers and toes articulate proximally with the intermediate phalanges at the distal interphalangeal joints (DIP).
What is the pelvis?
In human anatomy, the pelvis (plural pelves or pelvises) is either the lower part of the trunk, between the abdomen and the thighs (sometimes also called pelvic region of the trunk), or the skeleton embedded in it.
What are the hip bones?
The hip bone (innominate bone, pelvic bone or coxal bone) is a large, flat bone, constricted in the center and expanded above and below. In some vertebrae, it is composed of three bones; ilium, ischium, and pubis.
What is the femur?
The femur, or thigh bone, is the most proximal (closest to the center of the body) bone of the leg in tetrapod vertebrates capable of walking or jumping, such as most land mammals, birds, many reptiles such as lizards, and amphibians such as frogs.
What is the patella?
The patella, also known as the kneecap or kneepan, is a thick, circular-triangular bone which articulates with the femur and covers and protects the anterior articular surface of the knee joint.
