Unit 3 - Physiological bases of Behavior Flashcards
What are the eight (8) types of endocrine glands
Pituitary Gland
Pineal Gland
Thyroid Gland
Parathyroid Gland
Thymus Gland
Adrenal Gland
Islets of Langerhans
Gonads/Sex Glands
Name the two (2) laws governing the neurons
All or Nothing Law
Law of Dynamic Polarity
Other term for Endocrine System
Ductless Gland
Is composed of the pons, medulla oblongata and the cerebellum. It is connected to the spinal cord.
Hindbrain
Also known as the master gland. It secretes a number of hormones that affect the activities of almost all the endocrine glands.
Pituitary Gland
Carry messages or nerve impulses away from the brain
Motor or Efferent Neurons
Butterfly-shaped gland. It secretes thyroxine and idothyroxine which affect growth and metabolism
Thyroid Gland
What are the parts of Neuron
- Cell body or Cyton
- Dendrites
- Axon
What are the 12 pairs of cranial nerves
Olfactory – nose
Optic – eyes
Oculo-motor – eyes
Trochlear – eyes
Trigeminal – eyes, jaw, cheek, tongue
Abducent – eyes
Facial – face and forehead
Glossopharyngeal – tongue and pharynx
Vagus – neck, thorax and abdomen
Accessory – pharyngeal and laryngeal muscle
Hypoglossal – tongue
Vestibule-cochlear – ears
The basic structural and functional unit of the nervous system.
The Neuron or Nerve Cell
It is a long and stem-like structure running down the vertebral column. It is composed of nerves that lead to and from the brain.
The Spinal Cord
States that it is either that neuron reacts or not at all, but if it does react, it reacts with fullest strength
All or Nothing Law
Is found right on top of the midbrain and serves as a relay center of the impulses being sent to the brain areas
Thalamus
What are the two (2) main functions of spinal cord
- provide connector mechanisms
for reflex reactions - transmit messages to and from
the brain
Has two division; the adrenal cortex – which secretes cortin or adrenal androgens and adrenal medulla – which secretes adrenaline and noradrenaline.
Adrenal Gland
Made up of the brain and the spinal cord. The brain is house in the skull and the spinal cord is found in the vertebral column. It serves as the integrating mechanism of the entire human body
The Central Nervous System
Compose of all the nerve fiber that connect the receptors to the central nervous system and which further connects the central nervous system to the effectors.
The Peripheral Nervous System (PNS)
