Q

a major function of the nervous system where The brain and spinal cord are the major organs for processing sensory input and initiating responses. The input may produce an immediate response, be stored as memory, or be ignored

A

Q

a major function of the nervous system where The nervous system can stimulate or inhibit these activities ( e.g heart cells must contract at a rate that ensures adequate delivery of blood to all tissues of the body) to help maintain homeostasis

Q

a major function of the nervous system where Skeletal muscles normally contract only when stimulated by the nervous system; thus, the nervous system controls the major movements of the body by controlling the skeletal muscle. The Nervous system controls secretion from many glands, including sweat glands, salivary glands, and glands of the digestive system.

Q

this system consists of the brain and the spinal cord. The brain is located within the skull, and vertebrae. The brain and spinal cord connect with each other at the foramen magnum of the skull

Q

a division that transmits electrical signals, called action potentials, from sensory receptors in the body to the CNS

A

Sensory Division

17
Q

a division that Detects stimuli and transmits information via action potentials to the CNS

A

Sensory Division

18
Q

efferent “away” division

A

Motor division

19
Q

a division that transmits action potentials from the CNS to effector organs, such as muscles and glands

A

Motor division

20
Q

a division that Conducts action potentials from the CNS to muscles and glands

A

Motor division

21
Q

Motor division is divided into two subdivisions, what are these?

A

Somatic Nervous System and Autonomic Nervous System

22
Q

a subdivision of motor division that is voluntary/conscious

A

Somatic Nervous System

23
Q

allows you to decide to move your skeletal muscles, as when you raise your hand. The CNS generates action potentials that are transmitted by the SNS to the skeletal muscles of the arm.

A

Somatic Nervous System

24
Q

a subdivision of motor division that is involuntary/unconscious

A

Autonomic Nervous System

25
Q

controls your unconscious activities, such as contractions of smooth muscle, cardiac muscle, and secretion by certain glands.

A

Autonomic Nervous System

26
Q

ANS is subdivided into two divisions, what are these?

A

Sympathetic division and Parasympathetic division

27
Q

it is called the fight or flight division. In general, it is the most active division during physical activity

A

Sympathetic division

28
Q

it is called the rest and digest division. In general, it regulates the resting functions, such as digestion and emptying of the urinary bladder.

A

Parasympathetic division

29
Q

Bundle of many axons that connects CNS to sensory receptors, muscles, and glands

A
