ANATOMY SYSTEMS. Skeletal System The skeletal system includes all of the bones and joints in the body. Muscular System The muscular system is responsible for the movement of the human body. Cardiovascular System The cardiovascular system consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport.

5 days ago · human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue —the ligaments and the tendons —in intimate relationship with the parts of the skeleton. This article is concerned primarily with the gross ...

The pectoral girdleis where the arms attach to the axial skeleton. It’s made up of the clavicle (collarbone) and scapula (shoulder blade). There are two of each of these — one for each arm.
Each arm contains 30 bones, known as the: 1. Humerus. The humerusis the long bone of the upper arm. 2. Radius. The radiusis one of two long bones of the forearm, found on the thumb side. 3. Ulna. The ulnais the second long bone of the forearm, found on the pinky finger side. 4. Carpals.The carpals are a group of eight bones found in the wrist area....
The pelvic girdle, commonly known as the hips, is where the legs attach to the axial skeleton. It’s made up of two hipbones — one for each leg. Each hip bone consists of three parts, known as the: 1. Ilium. The iliumis the top portion of each hip bone. 2. Ischium.The ischium is a curved bone that makes up the base of each hip bone. 3. Pubis.The pub...
Each leg is composed of 30 bones, known as the: 1. Femur. The femuris the large bone of the upper leg. 2. Tibia. The tibiais the main bone of the lower leg. It forms the shin. 3. Fibula. The fibulais the second bone in the lower leg, found in the outer leg. 4. Patella. The patellais also called the kneecap. 5. Tarsals.The tarsals are the seven bone...
- Skull. The skull is composed of 22 bones that are fused together except for the mandible. These 21 fused bones are separate in children to allow the skull and brain to grow, but fuse to give added strength and protection as an adult.
- Hyoid and Auditory Ossicles. The hyoid is a small, U-shaped bone found just inferior to the mandible. The hyoid is the only bone in the body that does not form a joint with any other bone—it is a floating bone.
- Vertebrae. Twenty-six vertebrae form the vertebral column of the human body. They are named by region: Cervical (neck) - 7 vertebrae. Thoracic (chest) - 12 vertebrae.
- Ribs and Sternum. The sternum, or breastbone, is a thin, knife-shaped bone located along the midline of the anterior side of the thoracic region of the skeleton.
Oct 25, 2023 · Here’s a skeletal system diagram providing you with a broad overview of the two skeletons and the bones in the body: [Main bones of the skeletal system (anterior view)] The axial skeleton is essentially the midline, or central core region, and consists of the bones of the skull (cranium) together with the bones of the trunk.
3. The Skeleton Protects Vital Organs. The brain is surrounded by bones that form part of the skull. The heart and lungs are located within the thoracic cavity, and the vertebral column provides structure and protection for the spinal cord. 4. Interactions Between the Skeleton, Muscles, and Nerves Move the Body.

Sep 21, 2024 · Chemical composition of the body. Chemically, the human body consists mainly of water and of organic compounds —i.e., lipids, proteins, carbohydrates, and nucleic acids. Water is found in the extracellular fluids of the body (the blood plasma, the lymph, and the interstitial fluid) and within the cells themselves.
