Chapter 3 - The Total Response Mechanism Flashcards
An interdisciplinary field of study concerned with the st ucture, function, development and biochemistry of the nervous system
Neuro-science
Psychological bases of behavior
Neuro-science
Psychobiology
Neuro-psychology
The study of psychological nases of human behavior
Psychobiology
The field of psychology concerned with the neural and biochemical bases of behavior and mental processes
Neuro-psychology
Purpose of nervous system
To gather and process information
Produce responses to stimuli
Coordinate the working of the different cells
2 interrelated divisions of the nervous system
Central N.S.
Peripheral N.S.
Made up of the brain and the spinal cord
Central nervous system
Which connects the brain and the spinal cord to everything else in the body such as the sense organs muscles and glands
Peripheral nervous sytem
Is a large rope like segment of nerve tissue extending down the vertebral column
Spinal cord
Are simple, inborn, automatic responses of some parts of the body.
Reflexes
Also known as the startle reflex, is one of the infantile reflexes
Moro reflex
O e of the infantile reflexes. It is normal in children up to 2 yrs old, but it disappears just as the child ages and the nervous system becomes more developed
Babinski reflex
Os the reduction of the pupil in size in response to light
Pupillary reflex
Protected by the skull, is the organ of our body that most directly controls our thoughts, emotions, and motivation
Brain
Core of the brain
Hindbrain
Forebrain
Midbrain
Hindbrain
Medulla oblongata
Pons varoli
Cerebellum
It plays an important role in autonomic activities
Medulla oblongata
Made up largely by nerve fibers that connect higher and lower levels of the nervous system
Pons varoli
Role is to maintain posture and to smooth out coordinate complex muscular activities
Cerebellum
Serves as the link between hindbrain and forebrain, and has a special role in audio and auditory activities
Midbrain
Composes of two large cerebral hemispheres and a number of important structures within the central regions of the hemispheres
Forebrain
Forebrain
Thalamus
Hypothalamus
Cerebrum
2 important structures buried into the central reguons of the cerebral hemispheres
Reticular activating system
Limbic system
Important in activating the cortex of the cerebral hemispheres, has a significant role in consciousness, attention and sleep
Reticular activating system
It controls the state of arousal awareness
Reticular activating system
It is important in organizing activities needed to satisfy our basic motivations and emotional needs
Limbic system
2 divisions of the peripheral nervous system
Somatic ns
Autonomic ns
Skeletal ns
Somatic ns
Include sensory system and the motor nerves that activate skeletal muscles responsible for movement
Somatic ns
Is concerned with the activities of the body that make us alive
Autonomic
2 subdivisions of autonomic nervous system
Sympathetic nervous system
Parasympathetic nervous system
A system of ductless glands that regulates bodily functions via hormones secreted into the bloodstream
Endocrine system
Special chemical messengers known as ____ that are directly released into the bloodstream because they have no ducts pr structured passageways to the organs that they serve
Hormones
According to CLIFFORD MORGAN, it is the tendency of the body to maintain balance among internal physiological condition
Homeostasis
Major human endocrine glamds
Pituitary Thyroid Adrenal Pancreas Parathyroid Gonads
Body temperature
36.7-37.7
Hupothermia
Low body temperature
Huperthermia
High body temperature
Hypoglycemia
Low blood sugar
Hyperglycemia
High blood sugar
Symptoms of Diabetes Mellitus
Polydypsia
Polyfagia
Polyuria
Excessive or abnormal thirst
Polydypsia
Excessive eating or gluttony
Polyfagia
Excessive passage of urine
Polyuria or hydruria
Blood pressure
120/80
Hypotension
Low blood pressure
Hypertension
High blood pressure
Chemical substances which are secreted by organs called glands and affect the functioning of the organs
Hormones
Growth Stimulation Hormones
Insulin
Melatonin
Various hormones that produces by the adrenal glands are involved in emotion and response to stress
Enables glucose to move out the blood into the cells of the muscles and the other tissues
Insulin
Which os secreted by the pineal body, a small gland the within the brain. Appears to regulate certain biological rhythm
Metabolism
The outer layer which produces cortisone
Cortex
Inne rlayer produces epinephrime
Medull
Male sex hormones
Testosterone/ANDROGEN
Female sex hormones
Estrogen
Stimulates female secondary organ characteristics and behaviors and maintains pregnancy
Progesterone
