Flashcards in The Biological Approach and Biopsychology Deck (24):
1

Biological Approach

Emphasising the importance of physical processes in the body like genetic inheritance and neural function.

2

Genes

Made up of chromosomes, consisting of DNA which codes the physical and psychological features. Being transmitted from the parents to the offspring.

3

Biological Structure

The jigsaw puzzle of parts which form an organ, system or living thing.

4

Neurochemistry

Chemicals in the brain that regulate psychological functions.

5

Genotype

The particular set of genes that a person has.

6

Phenotype

How these genes are expressed, having been influenced by the genes (nature) and the environment (nurture).

7

Evolution

The changes in inherited characteristics in a population over extended amounts of time.

8

Nervous System

Made up of the Central Nervous System and the Peripheral Nervous System.

9

Peripheral Nervous System (PNS)

Sending information between the CNS and the brain. Along with transmitting information to the muscles and glands to create action.

10

Central Nervous System (CNS)

Consisting of the brain (2% of body weight) and spinal cord, being an organ of complex demands and decisions.

11

Somatic Nervous System

Transmitting information from the receptor cells in the sense organs to the CNS. Plus receiving information from the CNS that gives muscles instructions.

12

Automatic Nervous System

Consisting of the Parasympathetic and Sympathetic Nervous System. Transmitting information too and from bodily organs.

13

Sensory Neuron

Carrying info from the PNS to the CNS. They have long dendrites and short axons.

14

Relay Neuron

As it says on the tin, connecting sensory neurons to the motor and other relay or interneurons.

15

Motor Neuron

These connect the CNS to muscles and glands, having short dendrites and long axons.

16

Endocrine System

Instructs glands to release hormones directly into the bloodstream. These hormones are carried towards organs in the body.

17

Gland

An organ which synthesises substances like hormones, including: the pituatary gland, adrenal gland, testes and the ovaries.

18

The adrenal glands sit______________. The adrenal cortex produces_________ whereas the adrenal medula produces________.

On top of the kidneys. Cortisol. Adrenaline.

19

The ovaries produce___________ (spell it)

Oestrogen and Progesterone.

20

Adrenaline

Produced by the adrenal medulla. Has a large effect on the cardiovasular system.

21

Synaptic Transmission

How neighbouring neurons communciate with each other by sending chemical messages across the synaptic gap.

22

Excitation

When a neurotransmittors like adrenaline, increases the positve charge of postsypnatic transmittion. Increasing the likeilhood that the neuron will fire passing on the impulse.

23

Inbitiory

Serotonin increases the negative charge of the postsypnatic neuron. Decreasing the likelihood taht the neuron will fire and pass on the impulse.

24

The fight or flight response

The amydala is stimulated along with Short Term SAM and HPA Hazard to protect the body.
