There are two types of girdles in human body. They are pectoral girdle and pelvic girdle

What are girdles and?

Girdles are bony structures composed of one or more components. There are two girdles in the human body, the pelvic girdle found in the hip and the pectoral girdle found in the shoulder.

How many girdles does the human body have?

You have two pectoral girdles in your body. The pectoral girdle consists of the two bones that make up your shoulder: clavicle, or collarbone. scapula, or shoulder blade.

What are girdles in biology?

a bony structure to which the limbs of vertebrates are attached.

How many types of girdles are found in human body?

There are two types of girdles in human body. They are pectoral girdle and pelvic girdle. Pectoral girdle is shoulder girdle and is made up of collar bones and shoulder blades. Pelvic girdle is the hip girdle.

What is pectoral and pelvic girdle?

The pectoral girdle stabilizes the upper limbs on the thorax and allows a range of mobility at the shoulder. … The pelvic girdle transfers upper body weight to the lower limbs by articulating with the spine.

What is pelvic girdle?

pelvis, also called bony pelvis or pelvic girdle, in human anatomy, basin-shaped complex of bones that connects the trunk and the legs, supports and balances the trunk, and contains and supports the intestines, the urinary bladder, and the internal sex organs.

What are the 3 vital organs protected by a skeleton?

Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.

What bones form the upper limb?

In this section, learn more about the anatomy of the bones of the upper limb – the clavicle, scapula, humerus, radius, ulna and hand bones.

Where is the pectoral girdle located in the human body?

The shoulder, or pectoral, girdle is composed of the clavicles (collarbones) and the scapulae (shoulder blades). In humans the clavicles join the sternum (breastbone) medially and the scapulae laterally; the scapulae, however, are joined to the trunk only by muscles.

What are the 4 bones in the shoulder girdle?

INTRODUCTION. The shoulder girdle is made up of four articulations (sternoclavicular, acromioclavicular, glenohumeral, and scapulothoracic) and three bones (clavicle, scapula, and humerus).

What are the joints of the shoulder girdle?

The shoulder girdle is composed of the clavicle and the scapula, which articulates with the proximal humerus of the upper limb. Four joints are present in the shoulder: the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints, and glenohumeral joint.

What is the role of girdles in skeleton?

Girdles provide connection between the axial skeleton and limbs.

What is pubic bone?

The pubis, also known as the pubic bone, is located in front of the pelvic girdle. In the rear, the ilium and ischium form the bowl shape of the pelvic girdle. … The pubic bone is not visible outside of the body and joins the front-facing half of the pelvic girdle.

What is the difference between pelvis and pelvic girdle?

The key difference between pelvis and pelvic girdle is that the pelvis is a lower part of the trunk that composes several bones such as a pair of bones, sacrum and coccyx while the pelvic girdle is one of the two parts of the bony pelvis that composes two appendicular hip bones oriented in a ring.

Is femur part of pelvic girdle?

Acetabulum and the Pelvic Girdle The femur and the pelvic girdle have a very special relationship—it’s special in that it allows you to walk. … The pubis, ischium, and ilium have a hand in creating the acetabulum, the deep, hemispherical, cup-shaped depression (the socket) with which the head of the femur articulates.

What is the difference between shoulder girdle and pelvic girdle?

The shoulder girdle or the pectoral girdle is a set of 4 bones which connects to the arm on each side. The pelvic girdle consists of two bones: sacrum and the coccyx. The pelvic girdle is formed of paired hip bones each made up of ilium, ischium and pubis.

How many bones are in the pelvic girdle?

There are three bones of the pelvis: the hip bone, sacrum and coccyx.

Is the sternum part of the shoulder girdle?

The pectoral girdle consists of the clavicle and the scapula, which serve to attach the upper limb to the sternum of the axial skeleton. The scapula (shoulder blade) lies on the posterior aspect of the shoulder.

Which are carpal bones?

The carpal bones are bones of the wrist that connect the distal aspects of the radial and ulnar bones of the forearm to the bases of the five metacarpal bones of the hand. There are eight carpal bones, which divide into two rows: a proximal row and a distal row.

What are the 3 bones of the arm?

Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius). The term “broken arm” may refer to a fracture in any of these bones.

What are distal bones?

The distal bones (lateral to medial) are the trapezium (“table”), trapezoid (“resembles a table”), capitate (“head-shaped”), and hamate (“hooked bone”) bones. The hamate bone is characterized by a prominent bony extension on its anterior side called the hook of the hamate bone.

Which bones protect the brain?

The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.

Which organ supports the body when you sit down?

The 24 vertebral bones called the spine, or spinal column, are the most important structure in the body when it comes to sitting.

What tissues can be found in a bone?

Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.

What are armpit muscles called?

Pectoralis major: This large fan-shaped muscle stretches from the armpit up to the collarbone and down across the lower chest region. It connects to the sternum (breastbone). Pectoralis minor: The smaller of the pectoralis muscles, this muscle fans out from the upper ribs up to the shoulder area.

What is the difference between the shoulder girdle and shoulder joint?

The shoulder is not a single joint, but a complex arrangement of bones, ligaments, muscles, and tendons that is better called the shoulder girdle. The primary function of the shoulder girdle is to give strength and range of motion to the arm. The shoulder girdle includes three bones—the scapula, clavicle and humerus.

What is the elbow joint called?

TypeHinge jointClinicalFractures, epicondylitis, arthritis, venipunctures

What type of joint is present in elbow?

The elbow joint is a hinge joint that provides great stability and movement for performing daily activities. The strong muscles that extend across the elbow joint bring about actions like flexion, extension, supination and pronation enabling us to perform activities of daily living.

What type of joint is in the elbow?

The arm in the human body is made up of three bones that join together to form a hinge joint called the elbow. The upper arm bone or humerus connects from the shoulder to the elbow forming the top of the hinge joint.

What are the 5 joints of the shoulder?
