Answer: Option A. ->
Pectoral girdle - Acetabulum
:
A
:
A
The shoulder girdle or pectoral girdle is the set of bones which connects the upper limb to the axial skeleton on each side. In humans, it consists of the clavicle and scapula. The acetabulum is a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint.
The pelvic girdle is formed by the fusion of ilium, ischium, and pubis.
Answer: Option A. ->
Skeletal muscles
:
A
:
A
The peripheral nervous system (PNS) is under your voluntary control - the nerves that carry instructions from your brain to your limbs, for example. As well as controlling your muscles and joints, it sends all the information from your senses back to your brain.The autonomic nervous system (ANS) is a division of the peripheral nervous system that influences the function of internal organs such as the heart, stomach and intestines.
Answer: Option A. ->
1. Spinous process, 2. Vertebral arch, 3. Foramen, 4.Lamina, 5.Transverse process
:
A
:
A
Body – The body is the weight-bearing part of the vertebrae.
Vertebral arch -The arch is on the posterior aspect of the body and protects the spinal cord
Vertebral foramen -The opening through the arch is called the vertebral foramen
Processes-There are three different types of processes which serve as attachment points for ligaments and muscles and sites for moveable joints

Answer: Option A. ->
Malleus, incus, stapes
:
A
The three tiniest bones in the body form the coupling between the vibration of the eardrum and the forces exerted on the oval window of the inner ear. Formally named the malleus, incus, and stapes, they are commonly referred to in English as the hammer, anvil, and stirrup.

Answer: Option D. ->
Arthritis is an old person's disease.
:
D
The most common misconception about arthritis is that it's a disease only of old people. In actuality, arthritis can affect anyone at any age, not just the elderly including children, Young adults and middle aged.

Answer: Option A. ->
First seven pairs
:
A
First 7 pairs of ribs are attached anteriorly to the sternum, next 3 attached to a cartilage called costochondral cartilage and the last 2 pairs do not have any anterior attachment and hence called floating ribs.

Answer: Option D. ->
Titin
:
D
Titin is a large abundant protein of striated muscle. Titin's primary functions are to stabilize the thick filament, center it between the thin filaments, prevent overstretching of the sarcomere, and to recoil the sarcomere like a spring after it is stretched.
Muscles contract through the action of two proteins called actin and myosin along with regulatory proteins tropomyosin and troponin, control your voluntary movements.

Answer: Option A. ->
Myoglobin
:
A
Red muscles muscle fibres are dark red which is due to the presence of red haemoprotein called myoglobin.
Hemoglobin in its deoxygenated state has a low affinity for oxygen compared to myoglobin(it is present only in muscles)
Globulins, albumin, and fibrinogen are the major blood proteins.
Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in red algae and cryptophytes
