Anatomy Flashcards
It is the largest lobe responsible for concentration, abstract thought, information storage/memory, judgment and motor function. It also contains the Broca area
FRONTAL LOBE
This lobe analyzes sensory information and relays the interpretation of this information to other cortical areas and is essential to a person’s awareness of body position in space, size and shape discrimination, and right–left orientation
PARIETAL LOBE
It contains midbrain, pons, and medulla oblongata.
BRAIN STEM
It is located posterior to the parietal lobe, this lobe is responsible for visual interpretation and memory.
OCCIPITAL LOBE
this lobe contains the auditory receptive areas and plays a role in memory of sound and understanding of language and music.
TEMPORAL LOBE
It is a thick collection of nerve fibers that connects the two hemispheres of the brain, is responsible for the transmission of information from one side of the brain to the other.
CORPUS CALLOSUM
It regulates the pituitary secretion of hormones that influence metabolism, reproduction, stress response, and urine production.
Addtl: site of the hunger center and is involved in appetite control, regulates autonomic nervous system.
HYPOTHALAMUS
The outermost layer; covers the brain and the spinal cord. It is tough, thick, inelastic, fibrous, and gray.
DURA MATER
The innermost, thin, transparent layer that hugs the brain closely and extends into every fold of the brain’s surface.
PIA MATER
This contains motor and sensory pathways and also helps regulate respiration
PONS
What are the 3 layers of the meninges?
- Dura mater
- Arachnoid
- Pia mater
The space that contains CSF
Subarachnoid space
Gland that secretes different types of hormones
PITUITARY GLAND
The middle membrane; an extremely thin, delicate membrane that closely resembles a spider web. It contains the CSF in the space below it.
ARACHNOID
Its primary function is to regulate bodily functions like breathing, heart rate, blood pressure, and swallowing
MEDULLA OBLONGATA
This part of the brain integrates sensory information to provide smooth coordinated movement. It controls fine movement, balance, and position (postural) sense or proprioception
Key word: responsible for motor function
CEREBELLUM
It is a clear and colorless fluid that is produced in the choroid plexus of the ventricles and circulates around the surface of the brain and the spinal cord.
CEREBROSPINAL FLUID (CSF)
Normal CSF volume
Approx. 125-150 mL
It is a semipermeable membrane that protects the brain from harmful substances like chemicals from medications, and bacteria/viruses
BLOOD BRAIN BARRIER
2 major parts of the nervous system and its components
- Central Nervous System brain, spinal cord
- Peripheral Nervous system - cranial nerves, spinal nerves, autonomic nervous system
Parts of a neuron
- Dendrites
- Cell body
- Axon
The basic functional unit of the brain
NEURON
These are branch type structures for receiving electrochemical messages. (Will “catch” signals/interpret signals. Will send to axons)
DENDRITES
A long projection that carries electrical impulses away from the cell body. (Will fire signals to other nerves)
AXON
