Bio 252 Anatomy and Physiology 2 - Lab 3 Brain Anatomy

Flashcards for Anatomy and Physiology 2 Lab 3, focusing on the gross anatomy of the human brain.

Frontal lobe

Intellect, human consciousness, reasoning

Parietal lobe

Receives and evaluates “touch” sensory information

Temporal lobe

Receives and evaluates smell, hearing; mediates memory

Occipital lobe

Receives and integrates visual input

Falx Cerebri

Dural fold separating left and right cerebral hemispheres

Falx Cerebelli

Dural fold separating left and right cerebellar hemispheres

Tentorium Cerebelli

Dural fold separating Cerebellum from Occipital lobe

Longitudinal cerebral fissure

Separates the left and right hemispheres of the brain

Lateral sulcus

Separates temporal lobe from frontal and parietal lobes

Transverse fissure

Separates the cerebellum from the occipital lobe

Central sulcus

Separates the frontal and parietal lobe

Precentral gyrus

Primary motor cortex

Postcentral gyrus

Primary somatic sensory cortex

Medulla oblongata

Respiration, blood pressure

Pyramids of Medulla

Decussation of spinal motor tracts

Olives of Medulla

Relay information from basal nuclei to cerebellum

Pons

Sensory relay center, respiration

Cerebral peduncles

Descending motor tracts from cerebrum to brainstem

Superior colliculi

Visual reflexes of the head

Inferior colliculi

Auditory reflexes of the head

Thalamus

Relays sensory information to cerebral cortex

Pineal gland

Biorhythm controls

Hypothalamus

Central control for endocrine system

Mammillary body

Memory associated with smell

Infundibulum

Connects pituitary gland to hypothalamus

Pituitary gland

Secretes endocrine hormones

Amygdala

Memory associated with emotion

Putamen

Procedural memory

Caudate nucleus

Learning and basic movements

Cingulate gyrus

Emotion, behavior and motivation

Corpus callosum

Nerve tracts that connect the left and right hemispheres

Fornix

Connects hippocampus to hypothalamus

Hippocampus

Memory consolidation, spatial navigation

Superior Cerebellar peduncle

Nerve tracts connecting cerebellum to midbrain

Middle Cerebellar peduncle

Nerve tracts connecting cerebellum to pons

Inferior Cerebellar peduncle

Nerve tracts connecting cerebellum to medulla oblongata

Arbor vitae

Nerve tracts within cerebellum

Lateral ventricle

Secretes and circulates CSF

Third ventricle

Secretes and circulates CSF

Fourth ventricle

Secretes and circulates CSF

Median aperture

Exit point from 4th ventricle to subarachnoid space

Lateral apertures

Exit points from 4th ventricle to subarachnoid space

Interventricular foramen

Connects lateral ventricles to third ventricle

Cerebral aqueduct

Connects third ventricle to fourth ventricle

Choroid plexus

Ependymal tissue that secretes CSF in a ventricle
