1
Q

Telencephalon

A

The Cerebrum

Responsible for higher brain functions

2
Q

Cerebrum

A

Consists of an outer gray matter (cerebral cortex) and an inner white matter

3
Q

Cerebrum Structure

A

Two Cerebral Hemispheres

4
Q

Longitudinal Fissure

A

Seperates Cerebral Hemisphere

5
Q

Corpus Callosum

A

Axons that connect left and right hemisphere

6
Q

Gyrus

A

Raised area/elevation of cortex

7
Q

Sulcus

A

Depression or groove between gyri

8
Q

Frontal Lobe End Location

A

Ends at the central sulcus

9
Q

Central Sulcus

A

Seperates parietal and frontal lobe

10
Q

Motor Speech Area (Broca Area)

A

On left frontal
Controls motor functions involved with speech
If this is damaged, you can’t speak

11
Q

Primary Motor Cortex

A

Located in precentral gyrus of each frontal lobe

Controls voluntary skeletal muscle movement

12
Q

Parietal Lobe

A

Ends Anteriorly at Central Sulcus

Lateral Limits at a LAteral Sulcus

13
Q

What areas are in the Frontal Lobe

A

Motor Speech Area

Primary Motor Cortex

14
Q

Primary Somatosensory Cortex

A

Located in Postcentral Gyrus of each parietal lobe

Recieves sensory input from skin, muscle, joints

15
Q

Wernicke Area

A

Overlaps areas in both parietal and temporal lobes

Helps us understand written/spoken language

16
Q

What areas are in the Parietal Lobe

A

Primary Somatosensory Cortex

Wernicke Area

17
Q

What areas are located in the Temporal Lobe

A

Primary Auditory Cortex
Wernicke Area
Primary Olfactory Corex

18
Q

Primary Auditory Cortex

A

Interprets/distingushes sounds

Stores Auditory memories

19
Q

Wernicke Area (Temporal Lobe)

A

Involved in recognizing, understanding, or comprehending spoken or written language

20
Q

Primary Olfactory Cortex

A

Processes smell information and provides conscious awareness of smells

21
Q

Area of Occipital Lobe

A

Primary Visual Cortex

22
Q

Primary Visual Cortex

A

Works with other areas in the occipital lobe to distinguish and interpret visual images
Assembles pieces to create a picture

23
Q

Areas located in Insula

A

Primary Gustatory Cortex

24
Q

Insula

A

Deep to the lateral sulcus and involved with memory

25
Q

Primary Gustaory Cortex

A

Involved in processing taste information

26
Q

Receptors Definiton

A

A receptor is a structure that converts a sensory stimulus to a nerve impulse

27
Q

Types of Receptors

A

Exteroceptors, Interoceptors, Propioceptors

28
Q

Exteroceptors

A

Near surface of body
Stimuli from outside environment
Some are cutaneous receptors (Skin)
Special Senses (Sight, Smell, Taste)

29
Q

Interoceptors

A

Primary stretch receptors in smooth muscle of blood vessels and viscera

30
Q

Proprioceptors

A

Provides infromation about muscles, joints, and tendons
Sends information to cerebellum
Involves joint receptors, muscle spindles
