What is pectoral girdle 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 are the parts of the pectoral girdle?
components. 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 is a limb girdle in anatomy?
noun In anatomy, the bony or gristly apparatus by which a limb is attached to the trunk; the basis of the appendicular skeleton; the shoulder-girdle or hip-girdle; the pectoral or pelvic arch.
How many types of girdles are found in human body name them?
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 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 is girdle in biology?
a bony structure to which the limbs of vertebrates are attached.
How many bones are in the pelvic girdle?
There are three bones of the pelvis: the hip bone, sacrum and coccyx. These bones connect the axial skeleton to the lower limbs, and therefore play a role in bearing the weight of the upper body.
What bones are the pelvic girdle?
In discussing the pelvis, a distinction can be made between the “pelvic spine” and the “pelvic girdle.” The pelvic girdle, also known as the os coxae, Latin for “bone of the hip,” consists of the fused bones identified individually as the ilium, ischium, and pubis.
What joint actions occur at the shoulder girdle?
The shoulder girdle is a gliding joint (with slight rotation) where the clavicle articulates with the scapula, usually moving as a unit. The movements of the shoulder girdle include depression and elevation, upward rotation and downward rotation, as well as abduction and adduction.

What can limb girdle muscular dystrophy lead to?
Limb-girdle muscular dystrophy is a term for a group of diseases that cause weakness and wasting of the muscles in the arms and legs. The muscles most affected are those closest to the body (proximal muscles), specifically the muscles of the shoulders, upper arms, pelvic area, and thighs.
What causes limb girdle muscular dystrophy?
What causes Limb Girdle Muscular Dystrophy? LGMD is caused by mutations of genes that result in abnormal function of proteins in muscles, thereby causing progressive muscle weakness. The inheritance pattern of LGMD varies and different genetic defects may result in the same clinical symptoms in different patients.
What are armpit muscles called?
Along with the pectoralis major and pectoralis minor, the subclavius muscle forms the axilla or armpit. The subclavius moves the shoulder downward and forward. Serratus anterior is another muscle on the front of the chest.
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.
Is the clavicle part of the trunk?
The collarbone is a thin doubly curved long bone that connects the arm to the trunk of the body. Located directly above the first rib, it acts as a strut to keep the scapula in place so that the arm can hang freely.
What are the four bone shapes that were previously listed?
All 206 of the bones of the skeleton can be categorized into four types: long, short, flat, and irregular.
What is a girdle in the Bible?

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. Take a look at the femur (see image). The helmet-like structure highlighted in teal is the head.
Is the coccyx part of the pelvic girdle?
Pelvis The pelvic girdle is formed by a single hip bone. The hip bone attaches the lower limb to the axial skeleton through its articulation with the sacrum. The right and left hip bones, plus the sacrum and the coccyx, together form the pelvis.
What are the 4 bones of the pelvis?
The pelvis consists of four bones: the right and left hip bones, the sacrum, and the coccyx (see Figure 1). The pelvis has several important functions.
What type of bone is pubis?
Pubic bone (Pubis)TA21346FMA16595Anatomical terms of bone
Which bone is not part of the pelvic girdle?
Detailed Solution. The correct answer is Incus. The hip bones on the right and left sides together form a pelvic girdle. Incus is one of the three bones in the middle ear.
What is phalanx bone?
“Phalanges” is the plural form of phalanx. In anatomy, it refers collectively to the digital (finger and toe) bones in the hands and feet. There are 56 phalanx bones in the human body. The big toe (known as the hallux) and the thumb each have two phalanges, while the other fingers and toes each have three.
Where is the top of the pubic bone?
The mons pubis is located over the pubic bone and the pubic symphysis joint. The pubic bone is one of the three parts of the hip bone. It’s also the frontmost facing portion of the hip bone.
What is ulna bone?
ulna, inner of two bones of the forearm when viewed with the palm facing forward. … The upper end of the ulna presents a large C-shaped notch—the semilunar, or trochlear, notch—which articulates with the trochlea of the humerus (upper arm bone) to form the elbow joint.
What is shoulder girdle?
A pectoral girdle, also referred to as the shoulder girdle, connects your upper limbs to the bones along the axis of your body. You have two pectoral girdles in your body. The pectoral girdle consists of the two bones that make up your shoulder: clavicle, or collarbone.
What movements occur at the elbow joint?
Being a hinge joint, the only movements allowed by the elbow are flexion and extension of the joint and rotation of the radius. The range of motion of the elbow is limited by the olecranon of the ulna, so that the elbow can only extend to around 180 degrees.
What muscles elevate the shoulder girdle?
The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles. Depression is accomplished through the force of gravity and the actions of the latissimus dorsi, serratus anterior, pectoralis major and minor, and the trapezius muscles.
What is the life expectancy of someone with limb girdle muscular dystrophy?
In its most common form, Limb-girdle muscular dystrophy causes progressive weakness that begins in the hips and moves to the shoulders, arms, and legs. Within 20 years, walking becomes difficult or impossible. Sufferers typically live to middle age to late adulthood.
