nervous and endocrine Flashcards
Parasympathetic
Maintains bodily functions and restores the body back to relaxed or normal mode.
Sympathetic
Is activated when the body is in a state of dynamic role or stress
Autonomic Nervous System
This is associated with the involuntary control of body movements and has two divisions, sympathetic and parasympathetic.
Cranial nerves
Are nerve fibers that carry information in and out of the brain stem
Spinal Nerves
The nerves that carry motor and sensory signals between the spinal cord and the body.
Somatic Nervous System
This system is associated with the voluntary control of the body movements and organs
Spinal Cord
This connects the brain to the body and it controls simple musculoskeletal reflexes without input from the brain
Peripheral Nervous System
Connects the brain to the organs and limbs.
Brain stem
The part that connects the brain to the spinal cord, and it controls autonomic functions such as breathing, heart rate, digestion, circulation, and blood pressure.
Cerebellum
located under the cerebrum and controls the posture, balance, and coordination.
Cerebrum
This is located at the upper part of the brain and controls activity and thought
Brain
This is an organ within the skull and it functions as an organizer and distributor of information for the body.
Central nervous system
This is the main processing center of the whole body.
Nervous system
This is the body’s command center.
Anterior lobe
Releases hormones in response to stimulation
Posterior lobe
releases hormones produced by the hypothalamus itself
GH
Growth Hormone (growth of bones and body tissues)
TSH
Thyroid Stimulating Hormone (stimulates the thyroid gland to make thyroid hormones)
ACTH
Adrenocorticotropin Hormone (stimulates the andrenal gland to produce certain hormones)
FSH (female)
Follicle Stimulating Hormone (helps control the menstrual cycle and production of egg cells in the ovaries)
FSH (male)
Follicle Stimulating Hormone (helps control the production of sperm cells)
LH
Luteinizing Hormone (controls ovulation and helps with the hormone production)
TRH
Thyrotropin Releasing Hormone
GnRH
Gonatropin Releasing Hormone (triggers the sexual development)
