Biological Psychology and Parts of Brain Flashcards
Genetics, behaviors, and physical structures passed down/heredity
Nature
Contributions of environmental factors and experience to our physical structure and behaviors
Nurture
Actual alleles, individuals profile of alleles (instructions)
Genotype
Observable characteristics
Phenotype
How the team and environment of an individual impacts their phenotype
Epigenetics
Describe homozygous and heterozygous
Homozygous is having two of the same alleles for a gene while heterozygous is having two different alleles for a gene
Clear,plasma like fluid that flows from the ventricles into spaces within the meninges and flows around surfaces of brain and spinal cord
Cerebrospinal fluid
Located just above spinal cord and contains large bundles of nerve fibers that travel to and from higher levels of the brain. Manage his heart rate and blood pressure. Damage is equal to quick death
Medulla
Located between medulla and midbrain. Manages sleep, arousal, and facial expressions. Serves as a bridge between higher and lower portions of the brain and connects the cerebellum to the rest of the brain.
Pons
Located above pons.Involved in sensory reflexes, movement, and pain. Contains receptors for endorphins.
Midbrain
Connected to the brain via pons. Balance and motor coordination, contains more nerve cells then the rest of the brain. Damage is equal to settle deficiencies in perception, language, and cognition.
Cerebellum
Wideband of nerve fibers that connect the left and right hemispheres of the brain
Corpus callous
Runs length of the brainstem’s core from the upper medulla into the mid brain. Responsible for mood, arousal, and sleep.
Reticular Formation
Thin layer of neurons covering the outer surface of the cerebral hemispheres
Cerebral Cortex
Lobe of the brain responsible for complex cognitive processes and judgment. Damage equals difficulty in speaking, schizophrenia and ADHD
Frontal
