Q

Out of the 3 primary organ systems which is the most important?

A

the nervous system is the most important—it is the command center of the body. All movement (for exercise, sport, and daily activities) is dictated by the nervous system.

Q

What does the nervous system consist of ?

A

The nervous system consists of the brain, spinal cord, and nerves and is responsible for controlling the voluntary (conscious or deliberate) and involuntary (automatic) functions of the body and the mind.

A

CEREBELLUM

24
Q

The trunk of the brain, consisting of the medulla oblongata, pons and midbrain that continues downward to form the spinal cord.

A

BRAIN STEM

25
Q

The part of the brain where most neural integration occurs.

A

CEREBRAL CORTEX:

26
Q

The brain region responsible for motor movement and processing auditory and visual information.

A

MIDBRAIN

27
Q

The brain region responsible for posture, facial movement, and sleep.

A

PONS

28
Q

The base of the brain stem, responsible for involuntary functions like swallowing, sneezing, and heart function.

A

MEDULLA OBLONGATA

29
Q

The brain region responsible for relaying sensory and motor signals and regulating consciousness.

A

THALAMUS

30
Q

The cerebrum is divided into two hemispheres—the left hemisphere and the right hemisphere. The right hemisphere controls movements on the left side of the body, and the opposite is true for the left hemisphere. For example, if someone suffers an injury to one side of the brain, motor function on the opposite side will be affected. This “crossover” is known as

A

DECUSSATION

31
Q

Which brain hemisphere is responsible for language, logical processing, science and math, & controls muscles on right side

A

LEFT BRAIN HEMISPHERE

32
Q

which brain hemisphere is responsible for Spatial perception, Creativity,Intuition, & Controls muscles on left side

A

Right brain hemisphere

33
Q

How many lobes is each hemisphere divided into

A

4 (Each hemisphere is divided into four lobes)

34
Q

what are the four lobes each hemisphere is divided into

A

frontal, parietal, temporal, and occipital.

35
Q

is at the front of the brain and is involved in motor control, emotion, and language.

Frontal lobe

36
Q

The frontal lobe contains the _____ ______ , which is responsible for the planning and coordination of movement.

A

Motor Cortex

37
Q

The _____________, responsible for problem-solving, impulsivity, attention, and language, is also located in the frontal lobe.

A

prefrontal cortex

38
Q

The brain lobe involved in processing sensory information

PARIETAL LOBE

39
Q

The region of the parietal lobe responsible for processing sensations like pain, temperature, and touch.

A

SOMATOSENSORY CORTEX

40
Q

of the brain is on the sides (literally meaning “near the temples”) and processes hearing, memory, emotion, and some parts of language. responsible for hearing, memory, and emotion.

A self-regulating process by which the body maintains the stability of its physiological processes for the purpose of optimal function.

A

HOMEOSTASIS

46
Q

The neural tissue extending from the medulla oblongata to the lumbar region (lower back) of the vertebral column.

A

SPINAL CORD

47
Q

The 12 sensory and motor nerves extending directly from the brain.

Q

The PNS is comprised of what neurons

A

afferent and efferent neurons

50
Q

Motor neurons sending information from the CNS to the muscles to generate movement.

A

EFFERENT NEURONS
TIP: Efferent signals Exit the CNS. Both efferent and exit begin with the letter E.

51
Q

Sensory neurons sending information from a stimulus to the CNS.

A

AFFERENT NEURONS
TIP: Afferent signals Arrive at the CNS. Both afferent and arrive start with the letter A.

52
Q

The part of the nervous system in charge of controlling voluntary movement.

A

SOMATIC NERVOUS SYSTEM:

53
Q

The part of the nervous system responsible for involuntary functions and movement.

A

AUTONOMIC NERVOUS SYSTEM

54
Q

activated by stress-related activities and is often referred to as the “fight-or-flight” system because it elevates heart rate and increases cellular metabolism (energy use)
