central nervous system Flashcards
What makes up the central nervous system
Brain and spinal cord
CNS is bathed in what nutrition
Cerebrospinal fluid
Where is the brainstem and CNS
The lower part of the brain extending toward the spinal cord
What are the structures of the brain stem
The medulla, pons, midbrain, cerebellum
Control survival
The medulla
Roll in arousal, is crossover point for sensory motor
The ponds
Sensory relay and houses part of the reticular formation
Midbrain
Is used for motor coordination and balance often lost in boxers
The cerebellum
The limbic system consists of what
Hypothalamus, Thalamus, hippocampus, amigdala, basal ganglia
In the limbic system it is in control of human behaviors eating, fighting fleeing and sexual behavior
Hypothalamus
In the limbic system it relays for incoming sensory information visual, olfactory, auditory input,
The thalamus
It is in charge of storage of new
hippocampus
Connects learning experiences to emotional responses for example fear and
Amygdala
the system of subcortical structures crucial for planning and producing movement also including the substantia nigra and nucleus
The basal ganglia
The forebrain consists of what
Two cerebral hemispheres, right and left. The cerebral cortex and the Corpus Callosum
What are the four lobes of the cerebral
Occipital lobe, parietal lobe, frontal lobe, and temporal lobe
The lobe responsible for visual cortex
Occipital lobe
Somatosensory cortex, touch, spatial relations
Parietal lobe
Primary auditory cortex– left side is language and auditory process, hearing and memory
Temporal lobe
Middle of the brain that connects both hemispheres
The corpus callosum
Broca’s area
Language production, resulting in aphasia
Wernicke’s area
Affects comprehension of written or spoken language, patient can hear and but cannot read or understand
Made up of all the nerves that lie outside the brain and spinal cord comprised of the somatic and autonomic nervous
Peripheral nervous system and endocrine systems
In charge of walking running and skeletal movement connected to voluntary movement and saucer sensory receptors
Somatic nervous system
The afferent nerve fiber
Sensory outward in
The efferent nerve fiber
Motor, inward out
The system in charge of sweating, nerves that connect to the heart, blood vessels and glands controls all involuntary functions as in Organ function
The autonomic nervous system
Expanse energy, fight or flight, prepares the body for action
Sympathetic
Conserves energy, returns body to resting state
Parasympathetic
Glands that secrete chemicals into the bloodstream influencing sauce and
Part of the endocrine system
The endocrine system is controlled by what
The central nervous system through the hypothalamus
The master gland of the endocrine
Pituitary
Controls motivation and regulates body
Hypothalamus
Governs release of hormones
Pituitary
Controls how body Burns energy
The thyroid
Maintains calcium levels
Parathyroid
Governs the immune system
Thymus
Governs the immune system
Adrenal gland
Controls digestion
Pancreas
Influences reproduction in females
The ovary
Influences reproduction in males
The testes
