Frontal Lobe

Primary Motor Complex Prefrontal Cortex

Parietal Lobe

Primary Sensory Cortex Somatic Sensory Area

diencephalon

contains epithalamus, thalmus, hypothalamus conscious and unconcious sensory info and motor commands.

Arachnoid

contains lymphatic fluid and reduces friction between opposing surfaces

olfactory

receive info about hearing and smell

Which of the following parts of the brain is not matched correctly with its function?

hypothalamus: regulating body temperature cerebellum: maintaining posture medulla oblongata: contains cardiovascular center **cerebrum: adjusting blood pressure

epidural space

lies between the dura matter of the spinal cord and the walls of the vertebral canal.

medulla oblongata

connects the brain with spinal cord

Which of the following structures is the most superficial

dura matter

3 meningeal layers

dura matter arachnoid pia matter

The flexor reflex

is a withdrawal reflex. prevents a muscle from overstretching. prevents a muscle from generating damaging tension.

pons

links the cerebellum with the midbrain,dienphalon, cerebrum, and spinal cord

pia matter

separates arachnoid from the innermost meningeal layer

subdural space

separates the inner surface of the dura matter from the second menigal layer arachnoid

cerebellum

adjusts postual muscles for the body fine tuning movements

dura matter

tough outter most covering on the CNS

. All EXCEPT which of the following are shown in a cross section through a region of the spinal cord?

white matter surrounded by gray matter

reflex arc

1- arrival of the stimulus and activation of the receptor 2-the activation of sensory neuron 3-info processing by interneuron 4-activation of motor neuron 5 response perihpial effector

meninges

Dura Subdurale Space Arachnoid Subacahnoid space Pia Matter

Which cranial nerve is responsible for the motor innervation of pharyngeal muscles and parotid salivary glands?

IX

The brain region that automatically regulates heart rate and blood pressure is called

MEDULLA OBLONGOTA

Which cranial nerve is responsible for the sensory innervation of the anterior two-thirds of the tongue

VII

Which spinal cord structure(s) contains the axons of CNS motor neurons that control muscles and glands?

Ventral roots

Occipital Lobe

Visual association area Visual Cortex

somatic motor association area-premotor cortex

monitors activity in the primary senesory cortex. allows you to recognize a mosquito landing on your arm.
