Your Answer:
What muscle covers the greatest surface area in the body and is considered the
largest muscle in the body?
Essay: The skeletal system is an amazing creation of God. Discuss the bones (that
were covered in this course) located in the axial and appendicular skeleton. Also
discuss which bones form the following joints in the body: the shoulder, elbow, wrist,
hip, knee, and ankle joint.
The skeletal system is undoubtedly a remarkable creation of God. It provides the framework
and support for the human body, allowing us to stand tall, move freely, and protect our vital
organs. In this essay, we will explore the bones covered in this course, focusing on those found
in the axial and appendicular skeleton. Additionally, we will discuss the bones that form various
joints in the body, including the shoulder, elbow, wrist, hip, knee, and ankle joint.
The axial skeleton consists of the central axis of the human body, including the skull, vertebral
column, and rib cage. One of the most prominent bones in the axial skeleton is the skull, which
protects the brain and houses the sensory organs. It is composed of several bones, including
the frontal bone, parietal bone, temporal bone, occipital bone, and sphenoid bone, among
others. These bones come together to form the cranium, providing a sturdy protection for the
brain.
7/6/24, 3:22 PM

Moving down the axial skeleton, we encounter the vertebral column, which consists of 33
vertebrae. These vertebrae are categorized into ^ve regions: cervical, thoracic, lumbar, sacral,
and coccygeal. The cervical vertebrae are located in the neck region, the thoracic vertebrae
form the upper back, and the lumbar vertebrae make up the lower back. The sacral vertebrae
fuse together to form the sacrum, while the coccygeal vertebrae fuse to form the coccyx,
commonly known as the tailbone.
Lastly, the rib cage, consisting of 12 pairs of ribs, protects the lungs and heart. The ribs attach
posteriorly to the thoracic vertebrae and anteriorly to the sternum, forming a strong and
protective cage. The ^rst seven pairs of ribs are called true ribs, as they directly attach to the
sternum, while the remaining ^ve pairs are known as false ribs, with some of them only
attaching to the sternum indirectly or not at all.
Moving on to the appendicular skeleton, we focus on the bones that aid in movement and
locomotion. The appendicular skeleton includes the limbs and their respective girdles, namely
the pectoral girdle and pelvic girdle. The pectoral girdle, or shoulder girdle, consists of the
clavicle and scapula. The clavicle connects the sternum to the scapula, providing stability and
mobility to the shoulder joint. The scapula, or shoulder blade, is a gat triangular bone that
articulates with the humerus, forming the shoulder joint.
The elbow joint is formed by three bones: the humerus, radius, and ulna. The humerus is the
long bone in the upper arm, while the radius and ulna are the two bones in the forearm. These
three bones work together to allow movement at the elbow joint, enabling gexion and extension
of the arm.
The wrist joint, also known as the radiocarpal joint, is formed by the radius and various carpal
bones. The radius articulates with the scaphoid and lunate bones, among others, to form this
joint. The wrist joint allows for gexion, extension, abduction, and adduction of the hand.
Moving on to the lower limb, the hip joint is formed by the acetabulum of the pelvis and the
head of the femur. This ball-and-socket joint allows for a wide range of motion, enabling
activities such as walking, running, and jumping.
The knee joint, the largest and most complex joint in the body, is formed by the femur, tibia, and
patella. The femur, or thigh bone, forms the upper part of the knee joint, while the tibia, or shin
bone, forms the lower part. The patella, commonly known as the kneecap, protects the knee
joint and improves the mechanical eiciency of the quadriceps muscles.
Lastly, the ankle joint is formed by the tibia, ^bula, and talus bone. The tibia and ^bula are the
two bones in the lower leg, while the talus bone is located in the foot. This hinge joint allows for
dorsigexion and plantargexion of the foot, enabling actions such as walking and running.
In conclusion, the skeletal system is a remarkable creation of God. The bones of the axial and

The axial skeleton has 80 bones that include the following: • cranial • facial bones •
thorax (sternum and ribs) • Vertebral column ( vertebrae, sacrum, coccyx) The
appendicular skeleton has 126 bones of the upper and lower limbs plus the bones of
the pectoral and pelvic girdles that attach each limb to the axial skeleton.
Appendicular that include the following: • Clavicle • Scapula •humerus • ulna/radius •
Carpals • Metacarpals • Phalanges • Sesamoid • Pelvis bones •Femur • Tibia •Patella •
Fibula •Tarsals • Metatarsals 1. Shoulder: the joint is formed where the humerus
(upper arm bone) ^ts into the scapula (shoulder blade) like a ball and socket. Other
important bones in the shoulder include the acromion is a bony projection off the
scapula. The clavicle( collarbone) meets the acromion in the acromioclavicular joint 2.
Elbow: The joint is a complex hinge joint formed between the distal end of the
humerus in the upper arm and the proximal end of the ulna and radius in the forearm.
3. Wrist: The wrist is the joint that bridges the hand to the forearm. it is a collection of
multiple bones in joints to include the distal ends of the radius and ulna, 8 carpal
bones, and the proximal portions of the 5 metacarpal bones. 4. Hip: The acetabulum is
formed from parts of the ilium, ischium, and pubis. The acetabulum is a cup-shaped
socket on the lateral aspect of the pelvis, which articulates with the head of the femur
to form the hip joint. 5. Knee: Also known as the tibiofemoral joint, is a synovial hinge
joint formed between three bones, femur, tibia, and patella. Two rounded, convex
process known as condyles on the distal end of the femur meet two rounded, concave
condyles at the proximal end of the tibia. 6. Ankle: Consists of three bones, the tibia,
the ^bula, and the talus. The distal-most aspect of the ^bula is called the lateral
malleolus. Together, the malleoli, along with their supporting ligaments, stabilize the
talus underneath the tibia.

appendicular skeleton work together to form the framework and support for the human body.
Additionally, various bones come together to form joints such as the shoulder, elbow, wrist, hip,
knee, and ankle joint, allowing for movement and locomotion. Understanding the intricacies of
the skeletal system and its joints helps us appreciate the incredible design and functionality of
the human body.
