Exam 4: Part 2 Review

1. Sensory: Perceive stimuli in the internal and external environments; allows us to detect changes
2. Motor: Electrical signals for muscle contraction allowing for things like muscle contractions, digestion, heart beating
Integration: Coordinates receives and interprets sensory inputs and sends commands (outputs)

Electrical Synapses:
- Faster
- Direct Contact

Chemical Synapses:
- Slower
- Neurotransmitters

- Epidural Space
1. Dura Mater
- Subdural Space
2. Arachnoid Mater
- Subarachnoid Space (Cerebral fluid)
3. Pia Mater

Sensory
- Carries information/signals to the brain and spinal cord AKA Central Nervous System (CNS)

Motor
- Carries impulses away from the Central Nervous System (CNS) to effectors (Muscleslands)

1. Fibrous tunic
2. Uvea (Middle tunic)
3. Sensory tunic

Outermost layer; Cornea & Sclera

Middle layer; Chorrd, Iris, Pupil, and Suspensory Ligaments

Innermost layer; Photoreceptors (rods and cones that detect the patterns in light)

(II); Sensory: Vision

(III); Motor: Most eye movement, pupil constriction

(IV) Motor: Moves eye downward and laterally

(V); Both; Face sensation, mastication

(VI); Motor; Abducts the eye

(VII); Both: Facial expression, taste

(VIII); Sensory: Hearing, balance

(IX); Both: Taste, gag reflex

(X); Both: Gag reflex, parasympathetic innervation
