Endotherm
An animal that is dependant on or capable of the INTERNAL generation of heat
22 of 50
Ectotherm
An animal that is dependant on EXTERNAL sources of body heat
23 of 50
Cornea
Serving to transmit light to the eye, it is transparent tissues that covers the front surface of the eye
24 of 50
Iris
The coloured ring of tissue suspended behind the cornea and in front of the lens. It regulates the amount of light entering the eye by adjusting the size of the pupil
25 of 50
Optic nerve
Bundle of nerve fibres that carry visual messages from the retina to the brain
26 of 50
Pupil
A black circular hole in the iris that regulates the amount of light exerting the eye. It appears black
27 of 50
Retina
The light sensitive layer of tissue that lines that back of the eyeball. Sending visual impulses through the optic nerve to the brain
28 of 50
Pinna
Collects sound waves and channels them into the ear canal where the sound is amplified
29 of 50
Auditory nerve
Transmits signals from the internal ear to the brain
30 of 50
Audiotory Canal
Transmits sounds firm the pinna to the eardrum
31 of 50
Cochlea
Transforms the vibrations of the cochlear liquids and associated structures into neutral signal
32 of 50
Echolaoction
Biological sonar
Animal emits a sound wave that bounces off an object returning an echo that provides information about the objects distance and size.
33 of 50
Central nervous system
Peripheral nervous system
Brain and spinal cord
everywhere else
34 of 50
Afferent neurones
Carry signals from sensory receptors to the CNS and is activated by external stimuli
35 of 50
Relay/inter neurone
Carry messages between sensory and relay neurones (found in CNS)
36 of 50
Efferent neurones
Carry nervous impulses from relay neurones to effectors. Make sup motor neurones and are normally muscles or glands
37 of 50
Hypothalamus Function
Temperature regulation, thirst, hunger, sleep, mood, sex drive, release of other hormones within the body
38 of 50
Cerebral cortex function
Thinking, perceiving, producing and understanding language
39 of 50
Pons function
Arousal, autonomic function (breathing), relaying sensory information between the cerebrum and cerebellum, sleep.
40 of 50
Lymph nodes
Filter substances that travel through the lymphatic fluid
41 of 50
Lymph Vessels
Transport lymph away from tissues
42 of 50
The spleen
Fights invading germs in the blood. Controls level of blood cells.
43 of 50
Bone marrow
Manufactures bone marrow stem cells and other substances which in turn produce blood cells
44 of 50
The Thymus
Makes white blood cells called t lymphocytes which help to fight infection
45 of 50
Long bone
Longer than they are wide
The ends of these ones are covered in cartilage to aid shock absorption
46 of 50
Short bone
Approximately as wide as the are long and have a primary function of providing support and stability with little movement
47 of 50
Irregular Bone
Do not fall under any other category due to their non-uniform sharp (vertebrae)
48 of 50
Sesamoid bone
Usually short or irregular bones
Imbedded in a tendon
49 of 50
Flat bone
String flat plates of bone
Main function of providing protection to the bodies organs and being a beam for muscular attachment
