Brain
Spinal cord- a group of nerve fibers and tissues that are connected to the spine and connects most parts of the body to the brain.
Thalamus- two masses of grey matter that is in-between the cerebral hemispheres and relays sensory information.
Hypothalamus- in the front part of the brain underneath the thalamus that controls the autonomic nervous system and controls body temp and blood sugar.
Limbic system- a system of nerves and networks that interconnect with emotions, social behavior, and brain disorders (epilepsy).
Corpus callosum- band of nerve fibers connecting and carrying information through the two hemispheres of the brain.
Cortex- the outer layer of the gray matter of the brain. It associates with the high brain functions such as movement and coordination. (Grey matter- cell bodies).
Midbrain- central part of the brain stem developed in the embryonic system, causes body to react.
Hindbrain- lower part of the brain stem formed by the pons, medulla oblongata, and the cerebellum.
Medulla- lower part of the brain connected to the spinal cord and controls involuntary functions (heart-rate, blood pressure, and breathing)
Reticular formation- controls sensory information, muscle tone, cardiac and circulatory reflexes, and attention.
Pons- connects to the medulla and thalamus it affects sleep, dreams, and respiration system.
Cerebellum – back of the skull in vertebrates it coordinates and regulates muscle activity. (Balance, coronation, movement)
Somatic Nervous System- part of the peripheral nervous system its controls voluntary movements of the muscles and organs. (Sight, hearing, touch, smell, and taste.)
Autonomic nervous system- controls bodily functions such as breathing, heartbeat, and digestive process.
Sympathetic nervous system- responds to emergency information.
Parasympathetic nervous system- regulates standard function of the body such as breathing, heartrate and digestion.
Cognitive maps- mental representation of one person’s world.
Schemata- bias about our judgements an others.
Cerebral cortex- the four lobes, frontal lobe, parietal lobe, occipital lode, and temporal lobe.
Corpus callosum- thick band of 200 million nerve fibers and conveys information between the cerebral hemispheres.
Cerebellum- located in the back of the skull, it regulates the muscular activity.
Parietal lobe- processes sensory information, makes sense of visual information, and processes language and mathematics.
Amygdala- part of the limbic system and controls emotions, survival instinct, and memory.
Hippocampus- regulates long term memory and has a role in spinal navigation.
