The Brain Quiz

What are the three main parts of the brain?

• spine, ribs, skull

• cerebrum, cerebellum, and brainstem

• heart, lungs, liver

• stomach, intestines, kidneys

Which part of the brain is responsible for controlling movement and balance?

• cerebrum

• cerebellum

• frontal lobe

• medulla oblongata

What is the function of the cerebellum in the brain?

• Coordinating voluntary movements, balance, and posture

• Producing hormones

• Regulating body temperature

• Processing visual information

What is the function of the frontal lobe in the brain?

• Regulating body temperature

• Decision making, problem solving, and voluntary movement

• Memory storage and retrieval

• Processing visual information

What are some common types of brain injuries?

• Cuts, bruises, and scrapes

• Burns, frostbite, and sunburn

• Concussions, contusions, and traumatic brain injuries (TBI)

• Sprains, fractures, and dislocations

How does the brain typically recover from a concussion?

• Taking medication and ignoring symptoms

• Jumping jacks and intense physical activity

• Continuing with normal activities without rest

• Rest and gradual return to normal activities

What is a reflex arc?

• A type of organ in the body

• A type of bone in the body

• A type of muscle in the body

• A neural pathway that controls a reflex action.

Explain the process of a reflex arc with an example.

• A reflex arc involves a sensory receptor, sensory neuron, motor neuron, and an effector. When a stimulus is detected, the sensory receptor sends a signal through the sensory neuron to the spinal cord, where a response is sent through the motor neuron to the effector, resulting in a quick, involuntary reaction.

• A reflex arc involves only a motor neuron and an effector, bypassing the sensory receptor and sensory neuron.

• A reflex arc does not involve the spinal cord, it only occurs in the brain.

• A reflex arc starts with the effector sending a signal to the sensory receptor, then to the sensory neuron, and finally to the motor neuron.

What are the two main components of a reflex arc?

• hormones and neurotransmitters

• spinal cord and brain

• cerebellum and cerebrum

• sensory neuron and motor neuron

How does a reflex arc differ from a voluntary response?

• A reflex arc is an involuntary response to a stimulus, while a voluntary response is a conscious and intentional action.

• A reflex arc and a voluntary response are both conscious and intentional actions.

• A reflex arc and a voluntary response are both involuntary responses to a stimulus.

• A reflex arc is a conscious and intentional action, while a voluntary response is an involuntary response to a stimulus.
