pituitary gland

Answer 27

produces critical hormones that control various bodily functions

Question 28

peripheral nervous system

Answer 28

• refers to all of the neurones that lead to and from the central nervous system
• is divided into 2 groups

Question 29

what are the groups PNS is divided into?

Answer 29

somatic and autonomic nervous system

Question 30

somatic nervous system

Answer 30

nerves in this system will relay information from the sensory receptors to the central nervous system then relay that info from the CNS to the skeletal muscles which is usually involuntary

Question 31

autonomic nervous system

Answer 31

carries impulses from the CNS to the heart and other internal organs
