What are the bones that attach the limbs of the body?
The Appendicular Skeleton. The appendicular skeleton includes all bones of the upper and lower limbs, plus the bones of the pectoral and pelvic girdles that attach each limb to the axial skeleton.
What are the limbs attached to?
Limbs are attached to the pectoral girdle or pelvic girdle. The one bony element of the upper limb is the stylopodium, the two bones of the lower limb are the zeugopodium. The distal portion of the limbs, that is, the hands or feet, are known as autopodia.
What makes up the axial and appendicular skeleton?
The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum. The appendicular skeleton consists of 126 bones and includes the free appendages and their attachments to the axial skeleton.
How is the front limb attached to the axial skeleton?
The bones that attach each upper limb to the axial skeleton form the pectoral girdle (shoulder girdle). It is attached on its medial end to the sternum of the thoracic cage, which is part of the axial skeleton. The lateral end of the clavicle articulates (joins) with the scapula just above the shoulder joint.
What suture connects the left and right parietal bones?
Sagittal suture. Connects right and left parietal bones.
What part make on the axial skeleton?
In the human skeleton, it consists of 80 bones and is composed of six parts; the skull (22 bones), also the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column….

What makes up the appendicular skeleton?
The appendicular skeleton includes the bones of the shoulder girdle, the upper limbs, the pelvic girdle, and the lower limbs.
Is the femur part of the axial skeleton?
The axial skeleton includes the skull and all the cranial bones, the spine, the ribs and the hyoid bone. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
How are limbs and girdles part of the axial skeleton?
The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton. 1. Skull Bones Protect the Brain and Form an Entrance to the Body. The skull consists of the cranial bones and the facial skeleton. The cranial bones compose the top and back of the skull and enclose the brain.
Which is the only bone of the lower limb?
The Bones of the Lower Limbs. The lower limbs include the bones of the thigh, leg, and foot. The femur is the only bone of the thigh. It articulates with the two bones of the leg–the larger tibia (commonly known as the shin) and smaller fibula.
What makes up the tailbone of the human skeleton?
The coccyx, or tailbone, is formed by a fusion of four vertebrae. The bones of the human skeleton are divided into two groups. The appendicular skeleton includes all the bones that form the upper and lower limbs, and the shoulder and pelvic girdles. The axial skeleton includes all the bones along the body’s long axis.
How are the limb leads connected to the heart?
Given the electrode placements, in relation to the heart, these leads primarily detect electrical activity in the frontal plane. Figure 18 shows how the electrodes are connected in order to obtain these six leads. To explain derivation of the limb leads, lead I and lead aVF will be used as examples.
