Muscular system
What is the longest muscle in the human body?
Sartorium muscle
What does the digestive system do?
It breaks down food into nutrients the body can absorb and use for energy and growth.
What is the primary function of the cerebellum in the brain?
The cerebellum is primarily responsible for coordinating voluntary movements, maintaining posture, balance, and fine motor skills.
The trigeminal nerve corresponds to which pair of cranial nerves and has how many branches?
It corresponds to the fifth pair and has three branches.
Blood pressure is highest in which type of blood vessel?
Arteries receive blood under high pressure.
What is the function of tendons in the muscular system?
Tendons connect muscles to bones.
Where does most nutrient absorption happen?
Most nutrient absorption happens in the small intestine.
Which part of the brain is responsible for processing auditory information?
The temporal lobe, specifically the primary auditory cortex, is responsible for processing auditory information.
Which nerve innervates the diaphragm?
Phrenic nerve
When we check a person's pulse, what are we observing?
When we measure an individual's pulse rate, we are analyzing their heart rate - how many times the heart beats per minute.
What are the three main types of muscle tissue in the human body?
The three main types of muscle tissue are skeletal muscle, smooth muscle, and cardiac muscle.
What is the function of the large intestine?
To absorb water and electrolytes.
What is the main role of the corpus callosum?
The corpus callosum connects the left and right hemispheres of the brain, allowing for communication and coordination between them.
What is the sciatic nerve, and which regions of the body does it innervate?
The sciatic nerve is the largest nerve in the body, innervating the posterior thigh, most of the lower leg, and the foot.
What does the term "pulmonary circulation" refer to?
Blood flow between the heart and lungs.
Which muscle is responsible for flexion of the forearm at the elbow joint?
he biceps brachii is the primary muscle responsible for forearm flexion at the elbow joint.
Which enzyme is primarily responsible for the digestion of carbohydrates in the oral cavity?
The enzyme salivary amylase (also known as ptyalin) is responsible for breaking down starch into smaller carbohydrate molecules in the oral cavity.
What is the function of the hippocampus in the brain?
The hippocampus is involved in the formation, organization, and storage of long-term memories.
Which cranial nerve is responsible for eye movement and controls the superior oblique muscle?
The trochlear nerve (cranial nerve IV) innervates the superior oblique muscle, which helps rotate and depress the eye.
Which blood vessel is responsible for transporting oxygenated blood from the heart to the body?
The aorta. It transports oxygenated blood from the left ventricle of the heart to the rest of the body.
What is the primary function of the sarcomere in a muscle fiber?
It is responsible for the sliding filament mechanism, where actin and myosin filaments interact to shorten the muscle.
What is the role of the liver in digestion, particularly regarding bile production?
The liver produces bile, which emulsifies fats, making them easier to digest and absorb in the small intestine.
Which part of the brain is primarily responsible for regulating vital functions such as heart rate, breathing, and blood pressure?
The medulla oblongata, located in the brainstem, is responsible for regulating these vital autonomic functions.
The median nerve innervates which muscles in the forearm, and what are the consequences of its injury?
The median nerve innervates most of the flexor muscles in the forearm and some intrinsic hand muscles. Injury can result in conditions like carpal tunnel syndrome, causing weakness or loss of sensation in the hand.
What is the name of the structure that separates the right and left sides of the heart?
The septum (interatrial, interventricular)
