Consists of the cerebrum, thalamus and hypothalamus.

A

Forebrain

20
Q

What are the three (3) major division of the brain?

A

Forebrain
Midbrain
Hindbrain

21
Q

Neurons are grouped into three (3), What are these?

A
  • Sensory or Afferent Neurons
  • Motor or Efferent Neurons
  • Inter-neurons, Connector
    Neurons or Association
    Neurons
22
Q

Also known as the gland of childhood. It controls the activity of the reproductive organs. It secretes the hormone melatonin.

A

Pineal Gland

23
Q

Small bodies made up of clusters of special cells scattered all over the pancreas.

A

Islets of Langerhans

24
Q

Consist of the brain and the spinal cord.

A

The Central Nervous System (CNS)

25
Q

Covers the cranial sacral regions. It slows down the life activities. It restores the body-stored energy thus calming down the body after resolving a stressful and emergency situations

A

Parasympathetic

26
Q

Also called the gland of babyhood. It keeps an individual childish. It secretes thymosin. This gland helps in building up the immune system of the body.

A

Thymus Gland

27
Q

An elongated strand with one or several formations at the far end called end brush.

A

Axon

28
Q

Involved with the process of maintaining the biochemical equilibrium in the body or homeostasis.

A

Endocrine System

29
Q

Serves as the bridge between the hindbrain and the forebrain. It is also involved in auditory and visual activities.

A

Midbrain

30
Q

What are the two (2) peripheral nervous system

A
  • Somantic Nervous System
  • Autonomic or Visceral Nervous
31
Q

Carry messages or nerve impulses within the brain.

A

Inter-neurons, Connector Neurons or Association Neurons

32
Q

States that impulses travel only in one direction from neuron to neuron.

A

Law of Dynamic Polarity

33
Q

Carry messages or nerve impulses from the sense organ toward the brain

A

Sensory or Afferent Neurons

34
Q

Composed of the sympathetic and parasympathetic systems. This division of the nervous system is responsible for all involuntary movements within the body that keep us alive

A

Autonomic or Visceral Nervous

35
Q

Pea-shaped gland. It secretes parathormone which controls the calcium level in the blood.

A

Parathyroid Gland

36
Q

What are the 31 Pairs of spinal nerves

A

Cervical (neck) – 8 pairs
Thoracic region – 12 pairs
Lumbar region – 5 pairs
Sacral region – 5 pairs
Coccygeal region – 1 pair

37
Q

Is made up mostly of the nerve fibers running from one part of the brain to the others

A

Pons

38
Q

Is the most complex and largest part of the brain and considered as the seat of consciousness.

A

Cerebrum

39
Q

Covers the activities of the internal organs within the thoracic-lumbar regions. It activates and speed up life activities. It leads to increase adrenaline secretion by the adrenal gland that is needed for threatening or emergency situations.

A

Sympathetic

40
Q

Called little brain. It enables us to learn and develop our habits and skills. It regulates our tongue and jaw movements during speech.

A

Cerebellum

41
Q

Jelly-like and extra soft weighing about 1,400 grams. It is the master organ and is the busiest part of the body. It controls and directs all activities in the nervous system. As the master or the chief organ, it is responsible for the integration of the central nervous system and the peripheral nervous system.

A

The Brain

42
Q

Regulates the involuntary muscles responsible for our heartbeat, rate of breathing or respiration, swallowing and movements of the stomach and intestine.

A

Medulla Oblongata

43
Q

Keeps the balance of different body systems mainly because of its close involvement with the endocrine system which releases hormones inside the body. Considered as the seat of emotion. It maintains homeostasis by regulating some involuntary activities like body temperature, thirst and sexual drive as well as our emotional behaviors.

A

Hypothalamus

44
Q

Short branching processes whose function is to receive nerve impulses and carry them toward the cell body.

A

Dendrites
