Brain Regions
What is the function of cerebrum?
controls voluntary movements, sensory processing, cognition, emotions, and memory.
What is the function of the optic nerve?
transmits visual information from the retina to the brain.
What is the dura mater?
the tough, outermost layer of the meninges that protects the brain and spinal cord.
What is the function of the gastrocnemius?
helps flex the knee and plantarflex the foot.
What is the function of the cranial nerves?
control sensory and motor functions such as vision, hearing, taste, facial movement, and autonomic functions like heart rate and digestion.
What is the function of the cerebellum?
Controls balance, coordination, and fine motor skills.
What is the function of the oculomotor nerve?
controls most of the eye's movements and regulates pupil constriction.
What is the pia mater?
the delicate innermost layer of the meninges that closely covers the brain and spinal cord.
What is the function of the internal obliques?
help rotate and laterally bend the torso, and assist in trunk flexion.
Where is the homunculus located?
located in the brain's primary motor and sensory cortices, representing the body’s sensory and motor functions.
What is the function of the pons?
regulates breathing, communication between different parts of the brain, and helps control sleep and arousal.
What is the function of the trigeminal nerve?
provides sensation to the face and controls muscles involved in chewing.
Where is the arachnoid mater?
middle layer of the meninges, located between the dura mater and pia mater.
What is the function of the Teres Major?
helps extend, adduct, and rotate the arm inward at the shoulder.
What is the medulla oblongata?
part of the brain is responsible for regulating vital functions such as heart rate, breathing, and blood pressure.
What is the function of the thalamus?
relays sensory information to the brain's cortex for processing.
What is the function of the facial nerve?
controls facial expressions and sensation in the front of the tongue.
What is the purpose of the ventricles?
produce and circulate cerebrospinal fluid to cushion and protect the brain and spinal cord.
What is the function of the sartorius muscle?
helps flex, rotate, and abduct the thigh, as well as flex the knee.
What is the frontal lobe?
part of the brain is responsible for higher functions like reasoning, planning, and problem-solving.
What is the function of the midbrain?
controls functions like vision, hearing, movement, and the regulation of body temperature.
What is the function of the vestibulocochlear nerve?
transmits sound and balance information from the inner ear to the brain.
Why is cerebrospinal fluid so important?
cushions the brain, removes waste, and helps maintain a stable chemical environment.
What is the function of the serratus anterior?
helps move the scapula forward and upward, allowing for the raising of the arm and stabilizing the shoulder.
What is the amygdala?
brain structure involved in processing emotions, particularly fear and pleasure.
