Skeletal Structure and Functions
This is the largest bone in the human body, located in the thigh.
What is the femur?
This neurotransmitter is primarily involved in muscle contraction at the neuromuscular junction.
What is acetylcholine?
This organelle is known as the powerhouse of the cell, generating ATP through cellular respiration.
What is the mitochondrion?
This type of bond involves the sharing of electron pairs between atoms.
What is a covalent bond?
This muscle is located in the upper arm and ordinates from the scapula and inserts at the radius, primarily allowing for elbow flexion.
What is the biceps brachii?
This type of bone tissue is characterized by a porous structure and is found mainly at the ends of long bones, contributing to lightweight strength.
What is spongy bone?
This cranial nerve is responsible for the sensation of taste from the anterior two thirds of the tongue.
This type of connective tissue stores fat and provides insulation and cushioning for the body.
What is adipose tissue?
This molecule is the primary energy currency of the cell, providing energy for the various cellular processes.
What is adenosine triphosphate (ATP)?
This large muscle group in the back of the thigh is responsible for knee flexion and hip extension, inserted on the tibia and fibula.
What are the hamstrings?
This term refers to the natural process through which bones grow and change shape during childhood and adolescence.
What is bone remodeling?
The brachial plexus gives rise to several major nerves, including this nerve which moves the majority of the arm muscles.
What is the median nerve?
This type of bone tissue is dense and forms the outer layer of the bones, providing strength and support.
What is compact bone?
This region of the body refers to the front facing side.
What is the anterior (or ventral) region?
This muscle, known for its role in core stability, originates from the pubis and inserts at the costal cartilages, and is commonly targeted in exercises like crunches.
What is the rectus abdominis?
These bones are primarily involved in protecting vital organs and providing surface area for muscle attachment, such as the bones of the skull and ribs.
What are flat bones?
The sympathetic nervous system originates from this region of the spinal cord.
What is the thoracolumbar region (T1-L2)?
These cells are responsible for the production of bone matrices and play a key role in bone formation.
What are osteoblasts?
This region is located at the back of the knee and is significant for containing important blood vessels.
What is the popliteal region?
This broad muscle in the back originates from the lower spine and iliac crest, inserting into the humerus and is heavily engaged during pull ups and rows.
What is latissimus dorsi?
This process involves the formation of new bone tissue and is crucial for growth and healing.
What is ossification?
This neurotransmitter is primarily released by the sympathetic nervous system and is responsible for the “fight and flight” response.
What is norepinephrine?
This type of connective tissue connects muscles to bones and is known for its tensile strength.
What is tendon?
This body region is located in the upper limb and includes the area from the shoulder to the elbow.
What is the brachial region?
This deep muscle of the hip is essential for hip flexion and stabilization, originates from the lumbar vertebrae and inserts into the femur, and it's used in exercises like leg raises.
What is the iliopsoas?
