Brain and Behavior Changes Flashcards
one of the most important systems in our body because it is the main control and coordination system of the body
Nervous system
It manages the voluntary and involuntary processes, especially during learning.
Nervous system
Nervous system is divided into two major parts which are:
Central nervous system and Peripheral nervous system
Both cns and pns are responsible for
Transmitting and and receiving information throughout the body
Both cns and pns are responsible for
Transmitting and and receiving information throughout the body
Central nervous system parts
Brain and spinal cord
Peripheral nervous system can be divided into
Autonomic nervous system and Sumatic nervous system
Autonomic nervous system is divided into
two parts which are:
Sympathetic and Parasympathetic nervous system
connects the brain and the peripheral nervous system
Spinal cord
carries messages to and from the CNS
Peripheral nervous system
controls voluntary muscle movement and transmits sensory information to the CNS
Somatic nervous system
controls involuntary body functions
Autonomic nervous system
arouses body to release energy
sympathetic nervous system
calms body to maintain and conserve energy
Parasympathetic nervous system
Relatively small structure weighing 1400 grams and is only 2% of the total body weight.
Brain
The brain is made up of 3 major components, which are:
Cerebrum, cerebellum, and Brainstem
Skull or meninges or covering has three parts which are:
Dura mater
Pia meter
Arachnoid
outermost tough menynx
Dura mater
innermost menynx
Pia mater
lies between the two meninges; within the brain cavities which contains a fluid
Arachnoid
Arachnoid lies between the two meninges; within the brain cavities, which contains this fluid
Cerebrospinal fluid
Part of the neural tube between the cerebral hemispheres and the spinal cord
Brainstem
The brainstem is made up of 4 neural structures which are:
Pons, medulla, midbrain, and interbrain
●Lies above the spinal cord
●The lowest part of the brainstem
●Concerned with regulating breathing, heartbeat, blood circulation.
Medulla or myelencephalon
●Lies above the medulla
●Front of the cerebellum
●Plays a part in sleep, dreaming, left body coordination and arousal
Pons or metencephalon
Interbrain or limbic system (diencephalon) consists of two parts:
Thalamus and Hypothalamus
Part of the limbic system located in the centre of the brain
Thalamus
Relay sensory information from the lower part of the brain to the proper areas of the cortex
Thalamus (inner chamber )
Temperature regulation and emotional behaviour
Thalamus
●Superior to the pons
●Smallest and least differentiated structure of the brainstem
●Involves in the regulation of walking, posture, reflexes from head and eye movements.
Midbrain (mesencephalon)
Regulates Eating, drinking, and sexual behaviours
Hypothalamus
Regulation of stress response and
Deals with emergency situations
Hypothalamus
Regarded as the pleasure center as well as stress center
Hypothalamus
Closely interconnected with the hypothalamus
Limbic system
Also exert additional over some instinctive behaviour already under the regulation of hypothalamus and brainstem
Limbic system
Lies between the thalamus and the cortex
Hippocampus or sea horse
Plays a crucial role in long term memories and the storage of memories
Hippocampus/ sea horse
Control of appetitive, sexual, and aggressive behaviour
Amygdala or almond
Storehouse of emotional memories
Amygdala or almond
Life without amygdala is not a life stripped of personal meaning
False
Located at the back of the pons and medulla
Concerned with control and coordinates voluntary, rapid, fine motor movements
Cerebellum
Also involved in muscle tone, and maintaining equilibrium
Cerebellum
Uppermost and expanded structure of the neural tube
Cerebrum
Uppermost and expanded structure of the neural tube
Cerebrum
Two layers of the cerebrum
Cerebral cortex and medulla oblongata
•Also known as the outer layer of the cerebrum
•Also called the gray matter
•Processing of information
Cerebral cortex
●Also known as the inner part of the cerebrum
●Also called as the white matter
●Transfer of information
Medulla oblongata
●Also known as the inner part of the cerebrum
●Also called as the white matter
●Transfer of information
Medulla oblongata

Difficulty expressing spoken and written language
Changes in speech
Verbal memory issues
Impaired logic
Sequencing difficulties
Injuries on the right side of the brain can cause:
Impairments of attention
Left neglect
Memory issues
Decreased awareness of deficits
Loss of big picture thinking
Altered creative or music perception
-primitive behaviors
