Q

This structure has motor functions, but also deal with aggression, mood, foresight, motivation, and social judgements.

A

Frontal Lobes

20
Q

Divided into anterior and posterior portions

  • Anterior portion produces hormones which regulate other endocrine glands and directly affect target cells
  • posterior portion functions to store and release hormones produced by the hypothalamus
A

pituitary gland

21
Q

It is composed of the frontal, parietal, occipital, and temporal lobes.

A

Cerebrum

22
Q

This structure functions to integrate all sensory information from the body, and channels it into proper processing regions in the cerebrum

A

thalamus

23
Q

These structures function in integration of sensory information with the exceptions of vision, hearing, and smell

A

Parietal Lobes

25
Q

the structure that is the major integration system between various organ systems and the nervous system

A

hypothalamus

26
Q

A structure that processes olfactory information and contains centers for reflex movements involved in eating such as chewing, licking, and swallowing.

A

Mammillary Body

27
Q

The region that regulates the day/night cycle.

Secretes the hormone melatonin, which effects sleepiness

A

Pineal Body

28
Q

The part of the brain that contains the nerve tracts and physically joins the two cerebral hemispheres.

A

Corpus Collosum

29
Q

It is the origin for the trigeminal, abducens, facial, and vestibulocochlear cranial nerves

A

Pons

30
Q

At the base of the brain stem, it contains nerve centers for the regulation of heart rate, blood vessel diameter, respiration, swallowing, vomiting, coughing, sneezing, and hiccoughing.

A

Medulla Oblongata

31
Q

A structure that is located on the bottom-center of the brain where the two optic nerves cross

A

Optic chiasma

32
Q

located just below the frontal lobes, they function in the sense of smell

A

olfactory bulbs

33
Q

Also called “Mesencephalon”, it is located above the pons and is the smallest part of the brain stem.

A

Midbrain

34
Q

An endocrine gland directly attached to the hypothalamus

A

pituitary gland

36
Q

This part of the brain is involved in the regulation of posture and balance, fine motor control of skeletal muscles and repetitive movements

A

Cerebellum

38
Q

coordinates activities of both the nervous and endocrine systems, and between voluntary and autonomic activities.
It is also attached directly to the pituitary gland

A

Hypothalamus

41
Q

This lobe lies between the temporal bone and the lateral sulcus

A

Temporal Lobe
