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
